In real life, there are several restaurants that offer to customers a giant burger like the King Sloppy, and some of them have the provision that it you eat it within a certain time period, you don't have to pay for it. One such mammoth burger is the Grand Tsunami, available at the Corral Drive-In in Long Beach, Washington. It's a monstrous 10 lb. burger with a 5 lb. patty! It costs $27, compared to the King Sloppy's price of $75.
