Marty gives Steve's science frog the power of speech. Steve then refuses to disect the frog when he befriends it. Making an annoyed teacher and a happy frog.
When Marty DePolo dies after eating a six-month-old hamburger, he is chosen to be the guardian angel of his best friend Steve Beauchamp.
Fearing Steve will be rejected when he asks Jessica to go out, Marty pretends to be her when Steve calls. But rather than let him down gently, Marty sets up a date and, in an effort to save his friend from heartache, actually morphs into Jessica, turning a dream date into a nightmare.
