 In the pilot and early seasons, Potsie appeared with best friend Richie in the plots and appeared to be more savvy than him, a character trait that would be dropped by the writers.As the series progressed, and with the breakout character Arthur "Fonzie" Fonzarelli becoming close friends with Richie, Potsie became more commonly paired with Ralph in episodes, particularly when the pair rented an apartment together upon leaving high school.Like his friends, Potsie had his share of crushes on members of the opposite sex.
