3 pieces of string walk into a bar but the barman says "sorry, we don't serve pieces of string here", so they all leave. One of the pieces of string says to his friends "Hey, that's not fair, i'm going to go ask again". So he goes in but he is immediately stopped by the barman who says "Sorry, but we don't serve pieces of string here". The piece of string leaves and tells his friends. Then one of the othere pieces of string tassels his hair and tied himself into a knot and walks in. He is then told by the barman "Go away, we don't serve pieces of string!". The piece of string replies "No, i'm afraid not!"
