In hell and playing the part of the Devil, Larry drinks a martini and pours Harry some liquor. Harry takes his real life relationship experiences, barely changes the names of the people involved, and then writes novels and short stories about them, usually slamming those people and their behavior. He then tells the young man he's got one for him and where to take her. A fictitious Jewish character is portrayed as wacky in one sequence where she prays over anything and everything. Of course they're played for laughs and most adults won't find them remotely frightening.
