I jump at the slightest noise, so I have to imagine I'd crap my pants if a car blew up 3 feet in front of me.  A Los Angeles firefighter had a car blow up in front of him, and he didn't even blink. 

Seriously, big thumbs up to any first responders out there.  I've got a lot of respect for what they do and it goes with out saying that they do things on a regular basis I could never do.  This dude is BAD ASS!
