Mom asks Calvin why he's still in bed. Calvin replies that he doesn't feel good. Mom says his forehead seems warm and decides to take his temperature. Calvin says he can't be sick. It's summer vacation and there is no school to stay home from. This is his time. He yells that somebody owes him big for this.

The doctor is seeing Calvin. He tells Calvin he understands he's not feeling well. Calvin retorts that he's fine. He sits around torture chambers in his underwear for kicks. He asks to see the doctor's degree and calls him a quack. The doctor says he isn't going to hurt Calvin. He just wants to examine him. Calvin says that what's wrong is that he has Dr. Frankenstein for a pediatrician. The doctor whispers to the nurse to call the anesthesiologist. Calvin tells him his Dad is a lawyer and not to come near him.

Spaceman Spiff is in a dungeon on the planet Zog. A guard leads Spiff to the interrogation room. The inquisitor says he finally gets to meet the famed Spaceman Spiff. He trusts Spiff is enjoying his visit. Spiff calls him a maggot from Mars and says he'll never give in. Calvin is hiding behind the scale with the doctor on his knees telling Calvin not to make him recant his Hippocratic oath.

As they drive home, Mom tells Calvin he was a terror at the doctor's office. Calvin says he didn't get a shot because he fended the doctor off with a tongue depressor. Mom says he didn't need a shot and that his behavior was inexcusable. Calvin is just glad that the doctor couldn't get close enough to stick him. He says the doctor thinks he's a pink pin cushion in underpants. Mom tells Calvin she hopes he has a kid one day who puts him through the same things he's putting her through. Calvin replies that Grandma says that's what she used to tell Mom.
