AN OLD SAILOR

An old retired sailor 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.

Hes soon going at it as well as he can for a guy his age, but needing a little reassurance, he asks, How am I doing?

The prostitute replies, Well, old Timer, your're doing about three knots.

Three knots? He asks. Whats that supposed to mean?

She says, You're knot hard, your're knot in, and your're knot getting your money back.
