If he doesn't leave, stare at his pants then puke on his shoes.
But let's say he doesn't have any pants or shoes on, then what do you do? Tell him for every five seconds he stands there refusing to leave, you will call a team technical.
If he still refuses to leave, tell him the game is forfeit, you are going to see to it he is suspended from coaching for life, you will follow him to his house and burn it down and see to it that his son, the star player, has to go to Texas Tech.
There - that last one should be enough of a scare to get some action.
