A string is walking through the desert...

A string is walking through the desert. After being lost for days, the string makes it to a small town. Dehydrated, he stumbles into the first saloon he sees and asks the bartender for a glass of water. The bartender says, "Sorry, we don't serve your kind here". The string, confused, asks what the bartender means. The bartender points to a sign behind the bar that says NO STRINGS. The string leaves dejected and asks a stranger outside for some help, "Hey partner, I've been in the desert for days. I'm dehydrated and this place won't serve me because I'm a string. Think you could help me out?". The stranger agrees, but asks "How?". The string thinks for a moment and says "Well, why don't you tie me in a knot so I don't look so much like a string". The stranger obliges and takes a step back to look. The string asks, "How do I look?". The stranger isn't satisfied and responds, "It isn't too convincing, maybe if we fray you a little bit on top, it'll help". The string agrees and after getting his knot frayed out, asks again, "How do I look now?". The stranger is pleased this time and tells the string to give it a try. Feeling like a new person, the string marches back into the saloon and orders a water. The bartender takes a good, hard look at the string and asks, "Aren't you that string that came in here earlier?". The string responds confidently, "No sir, I'm a frayed knot".

(No sir, I'm afraid not)
