For refrerence, you're using audio events, and not streaming your audio. This is exactly why your audio is out of sync. Check out the tutorials in NG, either through the flashes or forums, and you'll see how to fix it.
If you want to get laughs, it needs to sound good too, no matter how funny the physical element is; if you disagree, I urge you to watch a sitcom muted.
Good luck in the future! :)
