Having spent all their cash and maxed out their credit cards gambling in Vegas, Peg and Marcy attempt to raise more funds by putting on a show, which leads to a hilariously bad rendition of the song Personality. Meanwhile, Al and the kids arrive in town to look for Peggy.
Bud is amazed when he discovers that his dim-witted sister is able to correctly predict the winning numbers on a roulette table by letting her mind go blank. He tells Al, who pressurises Kelly into giving him a number, thus losing their last eight dollars. In a last ditch effort to make some cash, Al enters a competition to survive three minutes in a wrestling bout with a G. L. O. W. girl for a prize of $10K not realising that his opponent isn't one of the sexier fighters but an enormous woman called Big Bad Mama.
You Gotta Know When to Fold Them: Part 2 delivers the hilarity that was missing from You Gotta Know When to Hold Them: Part 1, with Bud smooching a fat lady, Al imagining himself as a Bond-style womaniser ("The name's Bundy... Al Bundy."), and the very silly wrestling match that sees Al being tossed around like a rag doll ("How's he going to sell shoes with his head flopping around like that?").
