Jim Carrey is Chip Douglas, cable intaller. Raised on television sitcoms, he want life to look just like My Three Sons. And when he meets single guy Steven Kovacs (Matthew Broderick), he sees his chance for some serious male bonding. But Chip's idea of friendship-which includes physical assalt, a game of 'Porno Password' and a medieval joust-may be hazardous to Steven's health. In Chip's own immortal words, "I can be your best friend...or your worst enemy."
