Three strings went into a bar for some drinks.
The first string said "Drinks are on me" and proceeded to the bar and ordered 3 beer's. The bartender told the string "Sorry bud, we don't serve strings here".
The second string stated to the first, "You don't know how to handle bartender's, watch me". The second string goes to the bar and say's to the bartender "Hey bud, I want 3 beer's, and I want them now" and the bartender say's "Listen here, I told your buddy over there we don't serve strings here, so move along before you have a problem".
The third string who is the smartest of them all, say's "Let me show you how this is done". String #3 ties himself into a knot and fluffs up his end and proceeds to the bar to ask for 3 beer's. The bartender states, "Arent you one of them string's I have told to buzz off?"
The string replies with "No, I'm a frayed knot".
