10-Four Good Buddie.
I remember the joke that was going around during the CB craze:
I guy who had an IQ he thought was too high because he couldn't have a normal conversation with people -- he would start talking about physics and other heavy esoteric stuff everytime he had a conversation -- went to a specialist who lowered IQs. The guy sat down in a chair, the specialist put earphones on him that were connected to a machine, which he set to lower the guy's IQ to the point where he would still be very smart, but not too smart. To do this, the guy had to be connected for five minutes.
The specialist got a phone call, and ended up talking for 1/2 hour until suddently he remembered about his patient. He rushed back to the machine, turned it off, and learned that with this much time under the treatment his patient's IQ would be lowered to that of an idiot. The specialist took the headphones off the patient and asked "Are you OK?"
"10-Four Good Buddie. Everything is AOK," the patient replied.
