Two nuns were shopping in a supermarket and just happened to be passing the beer and liquor department. One nun asked the other if she would like a beer. The other nun answered that would be good, but she would be a bit uneasy about purchasing it. The first nun said she would handle it and picked up a six pack and took it to the cashier. The cashier had a surprised look, and the first nun said, "This is for washing our hair." Without blinking an eye, the cashier reached under the counter and put a bag of pretzels in the bag with the beer, saying, "Here, don't forget the curlers."
