very old joke:

girl sitting at a bar...a flashy guy with a leer sits down beside her.

"hey, pretty lady....would you go come with me to Acupulco for a week and sleep with me for $50,000?"
she looks at him, astounded..."hmmmm...you know, I just think I might do that!"

"Well", he says, "How about a quickie in the alley for 20 bucks?"
"WHAT?" she sputters, "What kind of girl do you think I am?"
"Oh". he says, "we've settled that...now we're just haggling over prices."
