I did this once in a lower level game. Told the kid operating the clock to delay restarting the clock for about 4 or 5 seconds (don't remember it exactly) - told him to just watch for me to chop it in. The ball is inbounded, and knocked right out of bounds. Inbounded and knocked out of bounds. Inbounded, pass - and out of bounds. all the while I'm still standing with my arm in the air! Never did it that way again.
