Peice of string walks into a bar... asks for a beer.
"sorry dude, we don't serve pieces of string in here", says the barman...
"oh" says the string, and leaves
String returns with a hat and moustache on
"nice try" says the barman... and tells the string to leave
String ruffles himself up, and tries for a 3rd time...
"c'mon" says the barman, "this is getting silly now"
"Dont know what you mean" says the string
"Well, you know the rules buddy.... you ARE a piece of string, aren't you?"
"No, I'm a frayed knot"
