A half-hour comedy series about Ted and how he fell in love. It all started when Ted's best friend, Marshall, drops the bombshell that he's going to propose to his long-time girlfriend, Lily, a kindergarten teacher. At that moment, Ted realizes that he had better get a move on if he too hopes to find true love. Helping him in his quest to find his future wife is Barney, a friend with endless, sometimes outrageous opinions, a penchant for suits and a foolproof way to meet women. When Ted meets Robin, he's sure it's love at first sight, but after a whirlwind romance with her, he realizes destiny has something else in store for him. The series is narrated through flashbacks from the future.
When Barney is forced to pick sides in a fight between Robin and his mother, Lily coaches him on how not to ruin his relationship. Meanwhile, Ted and Marshall get into a dispute over wedding gifts and thank-you notes.
