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.
