I'm guessing most of you have seen this as I've been like at least a week or two late in posting it but if you haven't you have to check out this video some player of the X−Box game Halo made.
Basically he went out and setup physics experiments by for example, placing vehicles in special places etc and blowing them up and watching the fireworks and stunts. What really makes it work is the sound clips he matched it with. Check it out if you haven't seen it. It's funnier than it sounds.
