Joanie Loves Chachi

With nothing to do during the day, on the advice of Chachi, Joanie starts hanging out with her roommate who attends college. On behalf of the band, she accepts an offer from the fraternity to play at one of their parties. Chachi thinks it would be beneath them to perform at such an event and becomes resentful of Joanie's new life. Meanwhile, Al tries to get in shape.
