The best practical joke I know of is from MASH. However, you need a reputation
as an incorrigable joker for it to work. Just let the person know you are
going to play a big one on him within 5 days. (Pick your time frame.) And
that he will be powerless to stop you. If you do it right, he'll worry himself
to pieces and make a fool of himself. Then DO NOTHING.

-if you have to ask get out of the way-
Have you ever been stopped by a traffic cop and, while he was
writing a ticket or giving you a warning, you got the feeling that
he would just love to yank you out of the car, right through the
window, and smash your face into the front fender?...
