The Old Sailors and the prostitute.

Felix and Oscar, two old retired sailor, put on their old uniform and head for the docks once more, for old times sake and some hot sex.



They engage a lovely prostitute and take her up to a room.



As Oscar watches, Felix is soon going at it as well as he can for a guy his age, but needing some reassurance, he asks, ‘How am I doing?’



The prostitute replies, ‘Well Felix, ya old sailor, you’re doing about three knots.’



‘Three knots?’ he asks. ’ What’s that supposed to mean?’



She says, ‘You’re knot hard, you’re knot in, and you’re knot getting your money back.’
