"Doctor Feldman! You better get into room 313 fast, the patient is acting bizarre!"
"I'm on my way!"
Entering the room the doctor sees the patient furiously tying and twisting pieces of rope together, drawn tight into a knobby mass. He seemed totally out of control.
"What are you doing? Stop that!" the doctor yells.
The patient completely ignores the doc and continues to loop and interlace the sections of rope in an intense, violent manner.
"Again, I beg you. Stop what you're doing. You're behaving in a mentally deranged way!"
To which the patient replies, "Say what you will doc, but I'M KNOT CRAZY!"
