Two strings walk to a restaurant. The first string walks in and tries to order, but the owner throws him out and yells, “I don’t serve strings in this restaurant!”
The other string messes his hair, ties an overhand in his midsection and walks in. The owner shouts, “Hey, didn’t you hear what I told your buddy?!”
The string says, “Yeah.”
The owner says, “Aren’t you a string?”
“The string says, “No, I’m a frayed knot.”
