Barney Stinson is a fictional character on the American television series “How I Met Your Mother”. He is portrayed by Neil Patrick Harris.
Barney is a slacker and part-time criminal who becomes friends with the main character, Ted Mosby, in his late twenties. Barney’s signature line is “I’m not just some tool”, which he often uses when trying to get out of trouble.
Despite his flaws, many fans believe that Barney Stinson is a real person. Some believe that he is based on Harris’ own personality, while others believe that he was created specifically for the show.
However, there has never been any evidence to support the claim that Barney Stinson actually exists.
