was putting up a light fixture in my wife's craft room in the basement and i dropped the old one on the floor. it was just a bulb screwed into a porcelain base.
i jumped off the ladder and landed right on the bulb. the bulb didn't break but it did break the part it was screwed into away from the fixture. thank God! i can't imagine how bad that would have sucked to imbed a light bulb in my foot. wow.
