"The Black Onyx Box" joke

The Black Onyx Box
A well dressed gentleman passes a curio shop and sees a beautiful black onyx box in the window. He likes it, so goes in to learn what it costs.
He asks the proprietor how much it is, and the proprietor says "$5,000".
"Wow," the gentleman says, "can I see what is in it that makes it so expensive?"
"Sure," says the proprietor and he opens the black onyx box. Inside is a beautiful realistic looking pussy.
The gentleman pulls his checkbook out when he says, "Hmmm, for $5,000 a pussy should be wet."
The proprietor picks up the black onyx box and flips a lid down on the side, exposing three buttons. He pushes one and instantly the pussy is wet.
The gentlemans mouth waters and takes his pen out but stops and says, "No, for $5,000 a pussy should be warm."
The proprietor pushes the second button, and instantly the pussy is radiating heat. The gentleman can feel the heat and starts to write the check and stops. "No" he says, "for $5,000 a pussy should smell."
The proprietor pushes the third button and instantly the room is filled with the aroma of pussy, enhanced by the heat and the wetness. The gentleman finishes writing the check and is about to hand it over when he says, "No, a pussy needs movement."
The proprietor, flips down a lid on the bottom of the black onyx box and pulls out a little crank and starts turning it. The pussy starts pulsating, the wetness dripping over the side and the heat and smell overpowering the gentleman.
The gentleman says, "I'll take it!" and hands over the check to the proprietor. The proprietor asks,
"Shall I wrap it?"
"No," says the gentleman,
"I'll eat it here."
