Me and a couple kids were partying and we were grillin up some burgers right? My friend turns on the gas some werid way, and leaves the cover closed for like five minutes and then comes back, opens the cover, and lights it. Boom. Swear to God, he burnt one of his eyebrows compleatly off. It is so damn ironic because we were planning on shaving one off anyway that night. It grew back in like two weeks. I always thought it took like four months.
