The third piece of string says to his friends, "Don't worry guys, I know a way", and disappears into the gents, ties a knot just above his head and pulls out the ends so it's all frizzy. He glides back into the bar and says to the barman, "Three pints of beer please." The barman looks at him a second, thinks, then asks, "Are you a piece of string?" "No, I'm afraid not!"
If you can name the source or author (the version above is paraphrased), you may have my sock. My chocolate sock.
P.S.: Read the ending aloud if you don't understand. I debated with myself about how I should spell it.
