 In the early seasons, Ralph was considerably "cooler" than Richie and Potsie, being a member of the gang, The Gems, and having a hot rod car.As the series shifted its focus to concentrate more on breakout character Fonzie and his friendship with Richie, Ralph was more often paired with Potsie.This was evident even more when the characters graduated from high school, when Ralph and Potsie rented and shared an apartment together, and they often argued.
