Child Molester and Priest

Alright, listen up, you dummy! This joke is about a child molester and a Catholic priest, right? The punchline is "They both prey at church." See, the word "prey" is used instead of "pray," because, well, priests do a lot of "praying" and the joke is that they "prey" on children. You are dumb because you don't know the difference between prey and pray.
