Warren 'Potsie' Weber is a fictional character from the sitcom "Happy Days". He was played by Anson Williams. Anson also played the character in several other shows: he appeared in guest appearances on "Love", "American Style" and "Laverne & Shirley".

'Potsie' was a close friend of Richie Cunningham and Ralph Malph, who often spent time at Arnold's Drive In. He was characterized as being not very bright, somewhat gullible, socially clumsy, and in modern hindsight, very "square", and because of it, he was frequently called a nerd by friends and acquaintances. However, Potsie is a very talented singer, and his musical endeavors became more central to the character as the series progressed. Potsie's extremely sour relationship with his father (never seen on camera) was a minor running joke on the series, with lines such as "I'm gonna talk to my dad too; will be the first time in six months!"

In "The Deadly Dares" (Season 1, Episode 6), Potsie revealed how he got his nickname. He was asked, "Potsie Weber? What kind of name is this?" He replied, "They call me Potsie because when I was a young boy I used to like to make things with clay, and one day my mother called me Potsie."
