Two pieces of string walk into a bar. The first one walks up to the bar and says, "Barkeep! Give me a beer!"
The bartender replies, "Well uh..aren't you a piece of string?"
The piece of string answers, "Yeah!"
And the bartender says, "Well get out of here! We don't serve your kind!"
So the first piece of string walks back towards the door.
The second piece of string says, "Hey wait, hold on a minute!"
"You're not doing it right, watch this."
He ties himself in a knot and frizzes out the top of his head. He walks up to the bar and says "Barkeep! Give me a beer!"
The barender said "Aren't you a piece of string?"
The piece of strings replies, "Nope, I'm afraid not!"
