A string walks into a bar and orders a drink.
Looking at the string, the bartender said,
"Sorry, we don't serve strings."
"What? That sucks," said the string.
So the string walks into the bathroom and ties himself up
and messes up his ends.
A couple moments later he comes back
out and approaches the bar again
and again orders a drink.
"Hey, aren't you that string?" asks the bartender.
"Nope. I'm a frayed knot."
