How I Met Your Mother is a comedy about Ted (Josh Radnor) and how he fell in love. When Ted's best friend, Marshall (Jason Segal, Freaks and Geeks), decides to propose to his long-time girlfriend, Lily (Alyson Hannigan, Buffy the Vampire Slayer), Ted realizes that time may be running out on finding the love of his life. His friend Barney (Neil Patrick Harris, Doogie Howser MD) is the anti-Marshall, a guy who thinks he knows everything about meeting women and isn't afraid to tell you. Ted first meets Robin (Cobie Smulders, Veritas the Quest), and he believes that she is the woman for him. Soon he realizes that he may not be right after all. Bob Saget (Full House) narrates the story with voiceovers as we follow along flashbacks from the future when he is telling his children the story of how he met their mother.
