Two nuns took their first trip outside the convent. They had never seen a baseball game, so they got tickets. Once inside, they sat in the bleachers, and hearing a vender selling hot dogs, one said, "We've never had hot dogs before," and they decided to order a couple.
The first nun unwrapped her hot dog, and proceeded to quickly wrap it up again, saying, "Oh, my!"
"What's wrong, sister?" asked her companion.
"Well," came the reply, "which part of the dog did you get?"
