Old Sailor

An old retired sailor puts on his old uniform and goes down to the docks once more for old times sake.

He hires a prostitute and takes her up to a room. He’s going at it as best he can for a guy his age.

The old sailor asks “How am I doing?”

The prostitute replies “Well sailor you’re about 3 knots”

“3 knots?” he say’s “What’s that supposed to mean?”

She say’s “Your knot hard, you’re knot in and you’re knot getting your money back!”
