There were these two strings walking down the road when they
came to a bar. They decided to stop in and have a few
drinks. So they sat down at a table and noticed that they
were not going to be served. So the first string said that
he would go up to the bar and get a couple of beers.
First string: Hey bartender, how about a couple of beers.
Bar tender: Sorry, but we don't serve strings here.
So the first string returned to the table and informed the second string
of the problem. The second string said "no problem, I'll take care of
this." So the second string stood up, Frazzeled his ends a bit and tied
himself into a knot. He then walked up to the bar..
Second string: Hey bartender, how about a couple of beers.
Bar tender: Hey, aren't you a string?
Second string: I'm a frayed knot... they got the beers...
