The Drew Carey Show 2x18

Drew returns disheveled and frustrated after a convention in Las Vegas. After losing his luggage and all of his money, a waitress named Diane took pity on him and they went out for drinks. She took Drew to a rock and roll chapel to get married and he went through with it, thinking it was a drunken prank. Unfortunately, the ceremony was legal. Diane admits she needed to get re-married in order to keep custody of her two kids. She convinces Drew to pose as her husband for a week to fool the social worker.
