Does anyone remember where Chachi lived during Season 11? His parents stayed in Chicago, so he must've lived with someone. I don't think it was Fonzie. My guess would be either Roger or Potsie. Anyone remember??

In one of the later shows, Potsie was on Chachi's back to "pay the rent" so it was assumed that Chachi had moved in with Potsie in Chachi's own mother's apartment complex.

Ah. Cool. Thanks Pat.
