Visiting a house of ill repute

Little Johnny goes into a house of ill repute and asks for a girl with gonorrhea.

The madam nodded and sent him upstairs to a room. Then she called one of her favorites for him.

The girl came into the room and started to undress, when he asked, "Do you have gonorrhea?"

"Gonorrhea? I should say not," she replied.

Little Johnny sent her back. The madam sent for another girl and said, "Honey, go upstairs and tell that fool you have the clap. Let's do what we can to make him happy."

The girl agreed, went upstairs and when Little Johnny asked, "Do you have gonorrhea?" she smiled and said, "Of course I do."

"Ok," he said, "Let's do it."

After it was over and they were laying side by side the girl said, "Listen Johnny, I don't really have gonorrhea"

Little Johnny smiled and said, "Well, you do now."
