Johnny Is Curious To Know

Little Johnny and his friend played in a vacant lot everyday, and across the
street was a brothel.  Day after day they saw men go up, knock on the
door, go in, and eventually come out happy and smiling.  One day they
became curious and decided to see what was going on.  The madam answers
the door and looks down at the boys, and asks what they want. They explain
what they saw, and tell her that they are curious as to what goes on inside.

The Madam thinks for a moment, shrugs, and says, "Do you have 5 dollars?"

Both boys dig deep into their pockets and come up with a total of 50 cents.
She says, "OK, that will have to do," as she proceeds to lift her skirt and
pull down her panties.  She tells both boys to take a sniff, which they do.
She closes the door and the kids proceed home.

About halfway down the block Little Johnny turns to his friend and says, "Ya
know Joey, I don't think I coulda stood 5 dollars worth of that."
