A guy walking down the street sees awoman with perfect breasts. He says to her "Hey miss, would you let me bite your breasts for 100 dollars?"

"Are you nuts?" she replies and keeps walking.

He turns around, runs around the block and gets to the corner before she does.

"Would you let me bite your breasts for 1,000 dollars?" he asks again.

"Listen sir, I'm not that kind of woman. Got it?"

So the guy runs again around the next block and faces her again: "Would you let me bite your breasts just once for 10,000 dollars?"

She thinks about it for a while and says, "Hmmm... 10,000 dollars, eh?"

"Ok, just once, but not here. Let's go to that dark alley over there."

So they went to that alley and she takes off the blouse to reveal the most perfect breasts in the world. As soon as he sees them he jumps on them and starts caressing them, fondling them, kissing them, burying his face in them....but not biting.

Finally the woman gets all annoyed and asks: "Are you gonna bite them or what?"
"Nah," he replies. "Costs too much."

Good one!

Excellent, reminds me of that old whore joke where the guy says at the end, We've already established what you are, now we're just haggling over price.
