Three strings walk into a bar. They ask the bartender for a drink. The bartender says "We don't serve strings here". They try a different bar with the same result.
One of the strings is getting frustrated, so he decides to tie himself in a knot and mess up his ends. He walks back into the bar and the bartender says "Hey, aren't you one of those strings I told to get lost?"
The string says "Nope, I'm afraid not (frayed knot)!"
Ok, shoot me.
