A priest, two priests, and a parrot walk into a bar.
Actually wait… the bartender is a parrot, and he was already there. The parrot says to the bartender "Why didn't you just say three priests?"
The first priest slowly inserts his fist into his own asshole. He works his way up to the wrist, then to the elbow. Soon enough, his entire arm up to his shoulder is wedged into his ass.
The second priest turns to the third priest and says "Well, I didn't ass-shoulder that one coming."
