Replying to Dumbest thing you did as a teenager?

Attempted to shoot fireworks out of my friends car (We did this on a country road at 2am). It was funny and all at first but then one blew up inside the car while we were gon 75. Scared the shit out the driver and he yanked the steering wheel. We slid sideways for a long ass time before coming to a stop. Sone of my friends were partially deaf for a few days. Looking back on it, that was such a dumb fucking idea. Thankful none of us were seriously hurt. Never mix fireworks with any other activity.
