At first, for an unmeasurable amount of time, there was nothing. Then came a sound, and everything was created.
4.5 billion years later we had Bruce Lee.
Though Bruce never decided to destroy the universe and send us all back to the nothing, he did have the power to do so.
During the filming of Way of the Dragon Chuck Norris challenged Bruce to a sparring contest. Bruce accepted, moved into a fighting stance, and breathed slowly inward, and then with his mouth, emitted the loudest sound ever heard.
All Earth's creatures became deaf.
Bruce later released us from our deafness by speaking, while breathing inwards, the word Hattaw.
Chuck decided to forfeit the match, Bruce had simply raised the stakes too high, and Chuck knew the universe could not survive a match of their combined magnitude.
