"Three Knots" joke
Finally getting a shore leave after being out to sea for a couple of months, the sailor made his way to a brothel and told the madam he wanted a lady for the evening.
The madam told him that they were very busy at the moment and he would have to wait. Having been at sea for such a lengthy time, he was impatient and told her he didn't want to wait. He asked if he could possibly have a go with her, if she wasn't busy.
After some price negotiations, she reluctantly agreed and they went up to a room.
The sailor proceeded to put his best moves on her and finally asked breathlessly, "Well, how am I doing?"
"I'd have to say you're doing about three knots," the madam replied.
"Three knots? What does that mean?" he asked.
"It's knot hard, it's knot in and you are knot getting your money back!" she replied.
