From X:
While shopping in the grocery store, two nuns happened to walk past the beer cooler.
One said to the other, “Wouldn’t a nice cold beer or two taste wonderful on a hot summer evening?”

The second replied, “It would indeed, Sister… but I’d feel uncomfortable buying beer. I’m sure it would cause a scene at the checkout.”
+
The first nun smiled and said, “I can handle that.”

She grabbed a six-pack and marched to the register. The cashier looked stunned as the two nuns stepped up with the beer. “We use it to wash our hair,” the nun said with a straight face. “It’s a sort of shampoo.”

Without missing a beat, the cashier reached under the counter, tossed in a pack of pretzel sticks, and said, “The curlers are on the house.”
