Miracle of miracles! After years of being perfectly comfortable with his "gross and disgusting" self, Louie (Danny DeVito) is suddenly anxious to turn over a new leaf. The reason? He has the chance to move into a plush co-op apartment -- a chance bolstered by the 48,000-dollar down payment he has borrowed from cabbie Jim (Christopher Lloyd). There's only one hurdle standing in his way: Louie must be approved by the ultra-snooty Co-op Board, headed by the ever-so-particular Mrs. Bascombe (Gayle Hunnicutt). Danny DeVito's fellow comedian-director Penny Marshall makes an uproarious cameo appearance.
