My grandma told me this joke and I felt like I needed to share it.

While shopping in a food store, two nuns happened to pass by the beer cooler. One nun said to the other, "Wouldn't a nice cool beer or two taste wonderful on a hot summer evening?"

The second nun answered "Indeed it would Sister, but I wouldn't feel comfortable buying beer as I am certain that it would cause a scene at the checkout counter."

"I can handle that without a problem" she replied as she picked up a six pack and headed for the checkout.

The cashier had a surprised look on his face when the two nuns arrived with a six pack of beer.

"We use beer for washing our hair" the nun said, "A shampoo, of sorts, if you will."

Without blinking an eye, the cashier reached under the counter, pulled out a package of pretzel sticks and placed them in the bag with the beer. He then looked the nun straight in the eye, smiled and said "The curlers are on the house."
