Potsie Weber
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.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!"Potsie was – along with Richie and Ralph, and later Chachi Arcola – part of a band that, in some episodes, performed at Arnold's Drive-In (and later, Fonzie & Big Al's) and other venues.Potsie,who eventually became assistant manager of Cunningham Hardware, the hardware store owned and operated by Richie's father, Howard Cunningham, was apparently smart enough to get into medical school, and continued to work toward his goal of becoming a psychiatrist during the later years of the show's run.
