Chest Cavity Puns

Bought some pizza slices and while I was filling up my drink from the soda fountain, there was a family of four talking about, of all things, medical professions. The daughter at the table said she thought a proctologist was basically a pervert since they'd be focused on butts all day every day.

The mom explained that you wouldn't call a heart surgeon who uses tools to literally crack open a person's chest cavity and muck around with things a serial killer, so why would you call a doctor who specializes in proctology a pervert?

The dad then chimed in "No that's not right... a serial killer is someone who uses Captain Crunch to murder another person!"

Silence at the table, and the daughter groaned rather loudly. I happened to make eye contact with the dad and just smirked and nodded, which made him beam, and walked out the door to hear him say "Right? Right guys?"

Well done, sir.
