How I Met Your Mother, Season 2
Ted and Robin are finally a couple.
A heartbroken Marshall must now go on and try to continue his life without Lily, and he reluctantly begins dating other people. Realizing she is not an artist, Lily returns to New York. She's reunited with Marshall, and the season culminates in their marriage. Barney loses a "slap bet," which permits Marshall to slap him in the face five times at any given time in the future, whenever Marshall chooses, which he has done two times through the course of this season. It is revealed that Barney has a gay, black brother (Wayne Brady). Also, Barney takes a trip to California to be a contestant on The Price is Right, in part because he believes that Bob Barker is his father, although he doesn't actually say so. They eventually find out that Robin was a Canadian teen pop star in the early 90s singing, most notably, "Let's go to the Mall." The music video, viewed by Barney hundreds of times, becomes a common joke during the show.
In the season finale, through a series of flashbacks, Barney learns from Ted and Robin that they had been broken up for some time before Marshall and Lily's wedding. They didn't tell anyone before because they did not want to take attention away from Marshall and Lily. Ted and Robin agree to stay friends as Ted wants to get married and Robin does not. The season ends with Barney excited at the prospect of Ted and himself being single guys on the town again. The final scene in season two ends with Barney and Ted on the balcony outside Lily and Marshall's wedding with Barney saying the beginning of, "Legen... wait for it..."
