A string goes into a bar, and orders a drink. The bartender takes one look at him and tells him "get lost string, we don't serve your type here!!!" Shocked, he walkes out and goes down the street to another bar. Upon walking in, the bouncer grabs him and says "we don't like your type here, beat it!". By now the string is getting a little pissed. Walking down the street towards another bar, he passes another string. He asks him "whatta you gotta do to get a drink in this town?" The other string, knowing what is happening right off the bat, tells him "you gotta take your top 6 inches and tie it in a knot, and the frazzle the ends all out. That will work around here." So, the string does as recommended, and goes back to the first bar.
He walks in and orders a drink. The bartender all the while giving him the evil eye, makes up his drink and serves him. The string's thinking this is great. It worked! Then, the bartender says to the string "you're not one of those strings, are you?"
The string replies, "no, I'm a frayed knot".
