Dad joke a version of which my Dad told:: A cannibal says to his friend, "I've been feeling so nauseous lately."

"Must've been somebody you ate."

"I think you're right."

"Who you eating these days?"

"Well, you know. Missionaries."

"How do you cook 'em?"

"Just boil them with some carrots and onions and a bay leaf or two."

"Describe these missionaries."

"Well, they wear sandals and brown robes, and they have bald heads with little tufts of hair on the sides."

"That's the problem. You're cooking 'em wrong."

"What do you mean?"

"Well, it's obvious. Those are friars."
