When St Peter asked a weird question to these Nuns

 approached St Peter and He made the same question:

“Sister, have you ever touched a penis?”

“Yes, I once gave a hand job.”

“Put your hand in the holy water and in you go.”

At this point one of the nuns at that back starts pushing and shoving her way to the front, when she gets there St Peter asks:

“Why are you in such a hurry?”

The nun replies:

“I have to gargle before sister Anne puts her ass in it.”
