Barney Stinson is one of five main characters on the CBS television series How I Met Your Mother. Opposed to his best friend, Ted Mosby, settling down, Stinson offers many strategies designed to help Ted meet women.[1] Through several seasons of the show, four of the main characters were couples, as Ted began dating Robin Scherbatsky and Ted's roommate Marshall Eriksen became engaged (and later married) to Lily Aldrin. This left Stinson the only single character, and, according to Neil Patrick Harris, who portrays the character, Stinson was "resentful" that the other characters had paired up.[2].
