I had an idea

Remember when light bulbs used to *POP* when they burned out? Well, last night the one in the bathroom was flickery, so I turned it off then turned it on so that I'd be ready for the inevitable jump I always do. Nothing. Just out. Now, come to think of it it's been a long time since I've been surprized when reaching into a dark room and flicking on the lights. Years, really. Is this a new function of lightbulb technology? I hope so 'cause I just HATE when that happens.
