So a string walks into a bar…

So a string walks into a bar. He hops up on a barstool and says, “Gimme a beer.”

The bartender looks at him, frowns, and says, “You’re gonna have to leave. We don’t serve strings here.”

The string says, “OK,” and hops off the barstool. He goes out the door and around the corner, ties himself a couple of times, frazzles himself at both ends, and goes back into the bar. He hops up on a barstool and says, “Gimme a beer.”

The bartender says, “Aren’t you the same string that I just sent out the door a minute ago?”

The string smiles and says, “No, I’m a frayed knot.” J.
