Barney Stinson is a character in an American Tv-show which is called How I Met Your Mother. Barney is not the star in this series, that is a guy named Ted, which is actually the guy that the whole series is about.
Barney is a good friend of Ted, and he appears in every single episode. One of the biggest reasons why I like Barney so much is that he is so incredibly funny, he makes me laugh in every single episode.
He also has a really cool personality, he is confident, good looking and has charm. He is really good at magic and picking up girls, picking up girls is sort of his main thing in life; he even wrote a really thick book of all the pick-up lines and tricks he uses to pick up girls.
