Colonoscopy Jokes Puns

So my dad being mid 50's with stomach issues had to get a colonoscopy. He goes under and as soon as he wakes up he says to this young female nurse, "I had a dream that I was in a prison movie."

My parents and I were eating dinner and talking about how Joan Rivers died after being put under anesthesia for a procedure that could have been forgone. My mom, a doctor, compared it to a colonoscopy in the sense that it is a routine procedure you get put under anesthesia for but you don't expect to die from.

Dad: Can't they perform colonoscopies now by having the patient swallow a pill with a camera?

Mom/Dr: They can but they won't be able to see the whole colon.

Dad: So, semicolon?

My dad is going to have a colonoscopy in the morning. I told her the news, then followed with...

"I sure hope my dad doesn't make an ass of himself tomorrow." She gives me a courtesy smile. So I try another...

"If he has any questions, I don't think he'll feel too shy to assssk." Nothing.

Then she says, "I hope the doctor has a good rebuttal for all these terrible jokes."

Boom. Roasted.
