In Springfield Elementary, the freezer is broken and all the food inside it will spoil. To turn it into something positive, Principal Skinner declares and 'All-You-Can Eat-Day' as a reward for excellent behavior. Bart, Nelson, Jimbo, Wendell and Milhouse create an eating contest. In the first round, everyone has to eat as many fish sticks as they can. Jimbo remembers he's allergic to fish and starts hallucinating and seeing Led Zeppelin. In the second round, everyone has to eat as many brussel sprouts as they can. Wendell is sick. In the third round, Milhouse, Nelson and Bart have a warm milk chug. Milhouse complains as he says he has lactose issues. He ends up going crazy and pouring his milk everywhere.
Around this time Skinner and Krabappel find out what is happening and wants to stop the contest but Edna makes it interesting by betting that Bart will win the contest and Skinner takes her up on it for going with Nelson. Mrs. Krabappel offers them some mint ice cream and Jiggly-O and they both don't give in. Bart is ready to quit but Lisa gives him some "advice" that he can't do it because Homer's eating contest escapades but Bart undoes his pants. Bart makes a 'hot dog sundae' by putting ketchup, mustard and cheese on his ice cream. In the end, Bart wins the eating contest and declares himself "son of Homer".
