Two nuns were shopping and happened to be passing the beer store.

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, "The beer is used for washing our hair." The cashier, without blinking an eye, reached under the counter and put a package of pretzels（椒盐脆饼干） in the bag with the beer, saying. . ."Here, don't forget the curlers."
