An old retired Boatswain's Mate puts on his old uniform and
heads for the docks once more, for old times sake.
He engages a prostitute and takes her up to a room.
He's 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, 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.
