How I Met Your Mother
How I Met Your Mother (often abbreviated to HIMYM) is an American sitcom that originally aired on CBS from September 19, 2005, to March 31, 2014. The series follows the main character, Ted Mosby, and his group of friends in New York City's Manhattan. As a framing device, Ted, in the year 2030, recounts to his son and daughter the events that led him to meet their mother.
Barney Stinson
Barney Stinson is one of five main characters on "How I Met Your Mother". He is a manipulative, oversexed businessman in his thirties who always wears a suit, likes women with "daddy issues" and is frequently willing to offer his (sometimes hypocritical) opinion. Throughout the earlier seasons, Barney is a huge womanizer, and has been described as a "high-functioning sociopath" by his best friend, Ted Mosby (Josh Radnor). Barney has a plethora of strategies and rules designed to meet women, sleep with them, and discard them. Through several seasons of the show, four of the main characters are couples, as Ted began dating Robin Scherbatsky (Cobie Smulders) and Ted's roommate Marshall Eriksen (Jason Segel) becomes engaged and later married to Lily Aldrin (Alyson Hannigan). This leaves Barney the only single character, and, according to Harris, Barney is "resentful" that the other characters have paired up. Later on, in season 5, he dates Robin. They end up breaking up not long after, once they both realize they are making one another miserable.
