Two nuns were shopping in a food store and happened to be passing the liquor section. One asks the other if she would like a beer. She said that would be good, but that she would be queezy 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 on his face and the nun said, "This is for washing our hair." The cashier reached under the counter and put a package of pretzels in the bag with the beer and said "Here, don't forget the curlers."
