Sorry about your friend dude.
That video made me laugh. I would've been pissed, though, if one of those cars on the street were mine, but the dude running the camera was hilarious.
A couple of 4th's ago a guy who lives around the corner from me saw us lighting fireworks and asked if he could bring over his launch tube because it pissed off the old man next door to him. The thing was loud...sounded like a cannon going off. Might have done something like that video if the tube fell over.
