Imagine you're put into T-Dog's situation. Zombies are lurking nearby, and you need to hide or you'll face unrelenting teeth ripping into your skin. First thing that comes to mind is "Crap! I need to find a place to hide." What does he do next? He gashes his arm on an open car door. Damn it, T-Dog. You missed the second step: mind your surroundings.  You don't just realize you need to hide and then run into objects like a friggin' blind man. You need to take a moment and analyze the environment. Look around before you put that hiding plan into motion. Seriously, when people are eating and ripping one another to shreds, how embarrassing is it to say "Yeah, I got this huge scar from a parked car." Don't make the same mistake T-Dog did.
