Time to end for end the staysail sheet..

A piece of string walks into a bar and the barman quickly tells him that
they don't serve string here.
The string runs outside, scruffs his hair up and puts his arms under his
legs.
Returning to the bar, the barman tells him the same thing.
"But I'm not a piece of string!"
The barman replies, "Are you sure?"
"I'm afraid knot."
