A piece of string walks into a bar...

"Hi, I'd like to be served please." Says the string.

"We cannot serve you, as you are only a string." Said the bartender.

Upset, the string comes out of the bar, tears apart his ends, and walks back inside.

"Hi, I'd like to be served please." Says the string.

"Aren't you just the string I said I won't serve?" The bartender asks.

The string says "Nope, I'm a frayed knot!"
