So a string walks into a bar with a few friends and orders a beer, right? The bartender says to him, "I'm sorry, but we don't serve strings here."So the string, he goes outside and hee ties himself in a loop and messes up the top of his hair. He walks back into the bar and orders a beer.
The bartender looks him over and says, "Hey, aren't you the string that was just here before?"
So the string says to the bartender, "Nope,sorry. I'm a frayed knot."
