Wii Sports Easter Egg - Throw the Bowling Ball Behind You

Start a game of Wii Sports Bowling. To throw the ball behind you, hold the Remote in a vertical position in front of your face. Hold the B Trigger (to start your Mii running). Suddenly draaw the Remote behind you in a downward swing, and let go just after the Remote points straight down.
If it works correctly The camera should follow the ball and pan behind you. The Miis behind you (usually other Miis you've created) and the audience will jump and scream (and jeer and applaud). Also, they'll pirourette (spin and jump).
This does not count as a throw.
