"What's that? Does it hurt?"

"It is a cattle prod. It hurts a little less than a branding iron."

- Calvin and his doctor, who shows an example of his sense of humor.

Calvin's doctor is a pediatrician with a wry sense of humor. As with most adults, Calvin isn't too fond of his doctor, and he is one of the few characters who terrifies Calvin. In one incident Calvin is out of control and the doctor asks for the anaesthesiologist.

He has been known to lose his temper.

Pretend Game Alter EgoEdit

Calvin also appeared as a doctor in among the Pretend Game Alter Egos, consulting with an adult alter ego of Susie. The doctor had very poor knowledge of medicine, regarding a mallet as an anesthetic and prescribing a lobotomy for foot pain which he claimed was psychosomatic.
