A piece of string walks into a bar. The string gets sloppy drunk, throws up everywhere, and gets banned from the bar. The next night, the string wants to get back in, so he ties himself in a knot, frazzles the top of himself, then walks in. The bartender looks at him suspiciously and asks, “Aren’t you that string that I threw outta here last night?” The string replies, “No! I’m a frayed knot!”
