A sailor goes to the local sex parlor to get laid. He sees the Madamme and says he needs to get laid. The Madamme says she requires that he shows he has money, of which the sailor produces a substantial roll of 20s. The Madamme then exclaims that will do nicely. She then tells the young sailor to go upstairs and first door on the right. The young sailor rushes up and pounds furiously on the door. Finally a voluptuos blonde answers the door. "cmon cmon, lets get it on" declares the sailor. Hold on says the blonde, I need to see money. "No prob" says the sailor as he drops her a 20. So the blonde starts in with the small talk. The sailor getting impatient says "Stop with the talk, I want to get it on!". So he tosses her another 20. So the blonde now starts doing a striptease. "Dammit girl! I want to get it on!". The sailor tosses out another 20. So they start with the loving. Time passes..................... The sailor asks the blonde "How am I doing?" She declares "Oh about 3 knots". "WHAT!" cries the sailor. "What do you mean by 3 knots!? "Well" she says "your not in, your not hard, and your not getting your money back"
