Short Order Crooks

S2, E35: When Monty has trouble making his famous Cheddarhead Charlie's Cheese Chowder, he and Zipper sneak into Ma's Diner to use her pressure cooker. At Ma's Diner, Fry (a bank robber) and Spud (Fry's assistant) con Ma into believing she won a trip to Miami in order to get her out of the diner so they can tunnel into the bank next door. Their plan backfires when the diner customers (mostly policemen from the police station next door) are served Monty's chowder and keep coming back for more, preventing Spud and Fry from digging their tunnel. Meanwhile, to keep Ma's business from going downhill, the Rangers make the cheese chowder every night till Ma gets back.
