Shampoo

While shopping in a food store, two nuns happened to pass by the
beer, wine, and liquor section. One asked the other if she would like
a beer.

The second nun answered that, indeed, it would be very nice to have
one, but that she wouldn't feel comfortable about buying it.

The first nun replied that she would handle that without a problem.
She picked up a six-pack and took it to the cashier.

The cashier had a surprised look, so the nun said, 'This is for washing
our hair.'

Without blinking an eye, the cashier reached under the counter and
put a package of pretzel sticks in the bag with the beer and said,
'The curlers are on me'.
