Slightly off subject. A penguin walks into a bar and asks the bartender, “Has my Dad been in here today?”
Bartender answers, “I don’t know. What’s he look like?”
Two strings walk into a bar.
The bartender says, “Hey, read the sign. No strings allowed.” He throws them out.
One string says, “He can’t get away with that!”. He ties a knot in one end of himself and loosens the threads so they stick out in different directions. He then marches back in.
The bartender said, “Hey, aren’t you a string?”
“Nope. I’m a frayed knot.”
