Two nuns were shopping in a food store and happened to be passing the beer
and liquor section. One asks the other if she would like a beer. The other
nun answered that would be good, but that she would be queasy about
purchasing it. The first nun said that 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."

The cashier without blinking an eye, reached under the counter and put a
package of pretzels in the bag with the beer saying, "Here, don't forget
the curlers."
