Three Strings

These three strings were having a hard time one night trying to
buy a beer. It seemed that because they were strings, they
weren't allowed to enjoy a beer upon entering a bar. The same
excuse..."sorry, we don't serve strings in here" only made the
strings more determined, but they always met with the same lack
of success. Exasperated, the leader of the strings had an idea.
While his string friends looked on, the leader snipped both ends
of himself and tied himself in a bowline. "Follow my lead", he
said to his buddies and entered a bar. "I'd like a beer please",
he said to the bartender. And to his surprise, the bartender
left and came back with a cool one. Just as the string was about
to sip his reward, the bartender asked, "pardon me, aren't you a
string?" To which the string replied, "no I'm a frayed knot."
