Two strings walk into a bar. The first tries to order something. "I don'tserve strings in this bar," the bartender says roughly and throws him out.The second ruffs himself up, ties his ends together, walks in, and orders."Hey, didn't you hear what I told your buddy?" the bartender says."Yeah," the string says."Aren't you a string?" the bartender says."I'm a frayed knot," the string replies.
