retired sailor

An old retired sailor puts on his old uniform and heads to 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 3 knots'.


Three knots he asks, 'What's that suppose to mean ?'


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