hile shopping in a food store, two nuns happened to pass by the beer, wine, and liquor section. One asked the other if she would like a beer.
The first nun replied that she would handle that without a problem. She just picked up the beer and took it to the cashier.
The cashier had a surprised look, so the nun said, "This is for washing our hair."
Without blinking an eye, the cashier reached under the counter and
"The curlers are on me."
