Moe tells Calvin he has two periods to live. He warns him that in gym class, Calvin will be turned into hamburger casserole. As Calvin walks off, he says he hates gym class. The coach thinks violence is aerobic.

Calvin gives his dinner a funny look. He plugs his nose and takes a bite. He turns green, purple, blue, orange and yellow as he flops around on the ground, acting as if he's choking. Mom sits him back in his chair and tells him it's hamburger casserole. She tells him there isn't anything in it he doesn't like. He takes another bite. He says that bite wasn't so bad. He was able to choke it down. He says his stomach pains aren't as bad. He says the secret is suppressing the gag reflex. Once he swallows it, he can stand it. Mom sits at the table saying she's glad the meal is such a hit.

Dad gets out of the car to see snowmen. One is lying face down, one bent over retching. Another is clutching at its throat. Inside, Dad asks Mom if they're having eggplant casserole. Mom says "why, yes".
