DAVID HAS A SORE ARM
You'd be sore, too, if you had recieved four inoculations the day before. Two in one arm, one in the other arm, and one in his -- as the nurse initially referred to it -- "rumpelstiltskin".
"Okay", said the nurse. "Now I need to give you a shot in your rumpelstiltskin!".
David reports that he had a hard time suppressing laughter. The effort caused him to pause, leading the nurse to think he hadn't understood her. She leaned over to him and whispered, conspiratorially, "Your BUTT! I need to give you a shot in your BUTT!"
David was nearly overcome by hilarity but he bit his lip and soldiered on.
When they emerged from the room the nurse announced to Mrs. Baslow that he "took it like a man."
