OLD SAILOR

Norman, an old retired sailor,
puts on his old uniform
and heads for the docks once more,
for old times sake and some hot sex.
He engages a lovely 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 Norman, 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.'
