In this segment from Lonely Planet, we learn how to throw a boomerang. It's not just a question of getting the boomerang to come back to you. Throw the boomerang the wrong way, and it just might come back to you like a heat-seeking missle! The host in this clip has trouble getting the boomerang to return, calling to mind the old joke: "What do you call a boomerang that won't come back? A stick."
