It reminds me of a game.
Several friends and I were playing Star Wars the role=playing game when the Game Master decided to take a turn for the silly. We, the players, suddenly found ourselves facing a small army of Sith Clown Troopers and were getting our asses handed to us when one of the players running a Jedi characters decided to use one of his force powers to create an illusion of a clown car. Naturally, the Clown Troopers failed their will rolls and couldn't resist the urge to all climb in the tiny vehicle. Once they were all in, another player had his character toss a thermal detonator under the illusion.
Bye bye Clown Troopers!
This certainly wasn't the last time the table descended into silliness, but it was certainly fun.
