Season One
In the year 2030, Ted Mosby (voiced by Bob Saget) sits his daughter and son down to tell them the story of how he met their mother.
The story begins in 2005 with Ted (Josh Radnor) as a single, 27-year-old architect living with his two best friends from college; Marshall Eriksen (Jason Segel), a law student, and Lily Aldrin (Alyson Hannigan), a kindergarten
teacher, and an aspiring artist. Lily and Marshall have been dating for
almost nine years when Marshall finally proposes. Their engagement
causes Ted to think about marriage and finding his soul mate, much to
the disgust of his self-appointed best friend Barney Stinson (Neil Patrick Harris), whom he met in the restroom at a bar. Barney is a serial womanizer
who concocts elaborate con games, usually involving costumes and fake
identities, designed to bed women he discards immediately afterward.
Ted begins his search for his perfect soul mate and meets an ambitious young reporter from Canada, Robin Scherbatsky (Cobie Smulders),
with whom he quickly falls in love. Robin, however, doesn't want to
rush into a relationship and the two decide to be friends. Future Ted
reveals that Robin is not the mother after referring to her as his
children's "Aunt Robin".
Ted begins dating a baker, Victoria (Ashley Williams),
whom he meets at a friend's wedding, causing Robin to become jealous
and realize she does have feelings for Ted. Victoria moves to Germany for a dessert fellowship, and she and Ted try a long-distance relationship.
Once Ted learns Robin has feelings for him, he tells her he broke up
with Victoria, even though he hasn't. They almost have sex when Victoria
calls and Robin answers, mistaking Ted's phone for her own. Ted and
Victoria then break up and an angry Robin distances herself from Ted,
but they eventually make up and decide to date.
Meanwhile, Lily begins to wonder if she's missed any opportunities
because of her relationship with Marshall, and decides to pursue an art
fellowship in San Francisco,
breaking up with Marshall in the process. The season ends with Ted
coming back to the apartment, the morning after spending the night with
Robin for the first time, to find Marshall sitting in the rain with
Lily's engagement ring, devastated by their sudden break up.
Season Two
Ted and Robin are now a couple; meanwhile, a heartbroken Marshall
tries to continue his life without Lily. After enduring numerous
emotional breakdowns, Marshall's friends step in, and Barney, using sly
catch phrases and pick up lines, tries to get Marshall back in the
dating game. Later, Lily, after finally realizing she is not meant to be
an artist, returns to New York.
She is reunited with Marshall, and the end of the season culminates in
their marriage. Also, everyone discovers Robin was a Canadian teen pop
star known as Robin Sparkles in the early 90s, with a hit single "Let's
Go To The Mall." In this time Marshall and Barney create a bet on
whether Robin was involved in "adult films." When Barney discovers that
he was wrong the popular "slap bet" was created which permits Marshall
to slap Barney in the face five times as hard as he can at any given
time in the future, whenever Marshall chooses, which he does twice
during this season. It is revealed Barney has a gay, black brother named
James (Wayne Brady). Also, Barney reveals Bob Barker is his father, unaware that his mother lied to him, and takes a trip to California to be a contestant on The Price is Right to meet his "father."
In the season finale, Ted reveals to Barney that he and Robin have
been broken up for some time due to their conflicting views on marriage
and kids. They didn't tell anyone in order to avoid taking attention
away from Lily and Marshall's wedding. The season ends with Barney
excited at the prospect of Ted and himself being single guys on the town
again, and ends the season with Barney saying, "This is going to be
legen- wait for it..."
Season Three
Barney begins the season with the word, "-dary!" Robin returns from a trip to Argentina with her new boyfriend, Gael (Enrique Iglesias),
and Ted must adjust to life as just her friend, while watching Robin
and Gael fawning over each other. Marshall and Lily decide to move out
on their own, falling in love with a place they can't afford. Robin
learns of Lily's bad credit rating due to her compulsive shopping for
popular brands, and forces Lily to tell Marshall. Despite this, they are
able to finally secure their dream apartment, only to discover it's in a
bad location and more poorly constructed than they thought (the floor
is tilted). Barney is slapped for the third time on Thanksgiving, which
Marshall dubs "Slapsgiving."
Ted tells his children he met their mother through a story concerning
her yellow umbrella. He finds the umbrella at a club and takes it home
after attending a St. Patrick's Day party where his future wife was,
although they did not meet. Ted attempts to woo Stella (Sarah Chalke),
a dermatologist he sees to remove an embarrassing butterfly tattoo.
This culminates in a memorable "two-minute date," which incorporates
small talk, dinner, a movie, coffee, two cab rides, and a goodnight
kiss, all within two minutes. Robin sleeps with Barney after he comforts
her following a break-up with a past Canadian love; Ted is infuriated,
and decides to stop being friends with Barney. Meanwhile, an unknown
woman begins to sabotage Barney's attempts to hook up. His saboteur is revealed to be Abby (Britney Spears), Stella's receptionist, with a vendetta against him for not calling her after they had sex.
In the season finale, after Ted and Barney get into separate car
accidents and end up in the hospital, they renew their friendship. It is
revealed Barney has true feelings for Robin, while Ted proposes to
Stella in an arcade.
Season Four
Stella says yes to Ted's proposal. Robin takes a new job in Japan,
but quickly resigns and returns to New York to attend Ted's wedding,
after realizing how much she misses her friends. Stella leaves Ted at
the altar to get back together with Tony, the father of her daughter.
Barney struggles with his feelings for Robin as his company shifts him
to the management team of a new acquisition, Goliath National Bank
(GNB).
Marshall and Lily move to their new apartment and debate over whether
or not they're ready to have children. Robin becomes roommates with Ted
and gets a job as an anchor for a 4 AM news show after Barney sends out
her video resume. Ted and Robin decide to sleep together constantly so
they won't fight over each other's bad co-living habits. Barney attempts
to make them stop fighting to prevent this, revealing to Ted his love
for Robin.
Ted finds out Lily has sabotaged all of his relationships with anyone
she doesn't approve of and indirectly may have inspired his breakup
with Robin. Robin and Ted end up talking about it, causing their
friendship to begin moving toward a positive note. After Barney finally
sleeps with his 200th woman (and rubs it in the face of the childhood
bully who taunted him into pursuing it), he begins to question the
purpose of the remainder of his life, leaving him more certain of his
feelings for Robin.
Ted, while carrying the yellow umbrella, bumps into Stella and Tony.
Tony later decides to visit him, sympathizing with Ted over his loss of
Stella. Tony offers him a job as a professor of architecture, which Ted
initially turns down.
In the season finale Robin finds out that Barney loves her, and
initially refuses to commit to anything but a sex-only relationship;
they seemingly end up together anyway. Ted decides that being an
architect is leading nowhere, and finally decides to instead to become a
college professor. The finale ends with Ted preparing to teach his
first class and Future Ted revealing to his kids that one of the women
in the class is their mother.
Season Five
Ted begins his job as an architectural professor, standing in the
middle of a classroom – although the mother was present, it turns out to
be an economics class as he's in the wrong lecture hall. Barney and
Robin have had a sexual relationship throughout the summer and Lily
locks them in a room, forcing them to come to terms with their
relationship. After a rough patch they decide to break up. Robin
describes it instead as "two friends getting back together." Barney
immediately goes back to his old ways, using the playbook to score with women. Throughout the season Barney and Robin show feelings of regret over their break-up.
Ted dates a graduate student named Cindy (Rachel Bilson)
and it is revealed her roommate is his future wife. Robin meets Don,
her new co-anchor on her 4 AM TV show. Though she initially dislikes
him, the two start dating and eventually she moves in with him. At the
end of the season they break up when Don takes a job in Chicago
— a job which Robin had previously turned down to stay in New York with
Don. Marshall uses his fourth slap on Barney, once again at
Thanksgiving. Ted buys a house, which needs to be fixed up badly, but is later revealed to be the future home for Ted and his kids.
Lily and Marshall are still unsure about having kids. After watching four doppelgangers of their group (Lesbian
Robin, Moustache Marshall, Stripper Lily and Mexican Wrestler Ted) they
decide to leave the big decision to the universe's "infinite wisdom"
and start trying when they have seen Barney's Doppelganger. In the
season finale, Barney disguises himself to have sex with a girl from
every country in the world, and Lily and Marshall mistake him for the
final doppelganger. When Marshall finds out, he decides not to tell
Lily, fearing she will want to wait even longer to have children. Lily
eventually finds out and decides to wait. In the season finale, Lily
thinks she sees Barney's doppelganger as a hot dog vendor, which causes
the group to realize she is seeing what she wants to see, and play
along. Eventually Barney agrees having babies is not a stupid idea and
Lily and Marshall should go forth. The season ends with Lily asking
Marshall to "put a baby in my belly."
Season Six
In the season opening, Ted sees Cindy again with a girl who he thinks
to be her roommate, but she turns out to be Cindy's girlfriend whom she
later marries. After prodding by Barney, Ted is eventually hired by GNB
once more as the architect of the bank's new headquarters (which was
originally scrapped in Season 4). However, he encounters opposition when
he meets Zoey Pierson (Jennifer Morrison),
a woman who is protesting against GNB for selecting a decrepit hotel,
the Arcadian, to be torn down for the headquarters. Over the season,
Ted's encounters with Zoey eventually blossom into a relationship after
she divorces her rich husband, but they break up as he puts his career
over love, leading to the Arcadian's demolition. Ted also resolves not
to get back with Zoey.
Having agreed to conceive a baby at the end of the previous season,
Lily and Marshall keep having sex, hoping she will get pregnant. Around
Christmas, they have a false alarm and later seek fertility testing.
However, tragedy strikes when Marshall's father passes away, leaving him
devastated and the gang comforting him. Marshall tries to get over his
father's death and live again. Despite a pledge to Lily to work harder
for their future, Marshall resigns from GNB and follows his dream of
being an environmental lawyer. Zoey also hires him as her lawyer in what
became a futile battle to save the Arcadian. At the end of the season,
Lily reveals that she is pregnant.
Barney finally admits to the gang that Bob Barker is not his real
father, especially when his mother decides to sell the house he grew up
in and his brother, James, meets his own father. Loretta offers the
identity of Barney's father on a sheet of paper, but Barney tears this
up after realizing her efforts as a single mother. At the funeral of
Marshall's father, Barney tells Loretta that he wants to see his father
at last. The man, Jerome Whittaker, is eventually revealed to be someone
whom Barney thought was his guardian. Barney is disappointed because
Jerome was not the free-wheeling man he knew as a child. Although he
tries to bring back Jerry's old ways, Barney admits that he wants to
settle down someday. He is also introduced to Nora, a co-worker of
Robin, for whom he develops feelings. After an initial falling out, the
season finale indicates a possible future revival of their relationship,
where Barney asks her for coffee and Nora tells Barney that "it's never
too late" to wear a sun-dress.
Robin continues to work at her talk show, Come On, Get Up, New York!, but the presence of a new hyperactive co-host forces her to leave. She is accepted as a researcher in another network, World Wide News.
The gang also discovers more of her past as the Canadian pop star Robin
Sparkles. Robin also encounters a man she has had a secret crush on
since first seeing him when she and Ted were dating, and Future Ted
hints that there will be more of him later.
A short scene during both the first and last episode of the season
feature a wedding set sometime in the future, which is where Ted will
meet his future wife. In the last episode it is revealed to be Barney's
wedding.
