It was a really hot day and a piece of string was walking along the road with the sweat pouring from him. He decided to go into a pub for a long cool drink. He approached the bar and asked the landlord for a pint of beer, to which the landlord pointed at a sign above the counter that said "Pieces of string not welcome here - we do not serve pieces of string." Again the piece of string asked for a pint and the landlord who was by this time becoming annoyed said, "Can't you read the sign?" The piece of string said "I can" and the landlord asked "well then, are you a piece of string?" To which the piece of string replied "No, I'm a frayed not!!!!" (not the best version Ed, but you can get the idea!!)
