A ten year-old-boy goes into a house of ill repute. He goes up to the madam and says, "I wanna buy a woman"

The madam says, Get outta here. You’re too young."

The kid reaches into his pocket and pulls out a huge wad of money.

"Well", says the madam, looking at the bills, "we might be able to work something out. What exactly did you have in mind?"

The little boy says, "I want a woman who has syphilis."

"Are you kidding me?" says the woman.

"Nope," says the kid. "I want a woman who has syphilis."

"OK, it’s up to you", says the madam, picking up the telephone. She calls the worst place in town, and they send a woman over. The boy goes upstairs with the woman, has sex, and comes down and pays the bill.

"Thank you", he says, and starts to walk out..

"Wait a minute, wait a minute", says the madam. "Come here".

So the kid walks over to her. "Yes?" he says.

"I can understand you wanting to come in here", she says, "but I don’t understand why you wanted a woman who has syphilis. Can you explain that to me?"

"Sure", says the kid "That’s means I got syphilis, right?"

She says, "Yeah..."

"And that means when I go home and get the maid tonight, that means she’ll have syphilis too, right?"

"Right", says the madam.

"Then when the butler gets the maid, he’ll get syphilis too, right?"

"Right", says the madam.

"Then when the butler gets Mommy, she’ll have syphilis, right?"

"Right", says the madam.

"Then, when Mommy gets Daddy, he’ll have syphilis, right?"

"Right", she says.

"Then, whe daddy gets the gardener’s wife, she’ll have syphilis, right?"

"Right", says the curious madam.

"Then when the gardener’s wife gets the gardener, he’ll have syphilis, right?"

"Right", says the madam.

"Well, that’s the jerk who killed my turtle".
