my new toothbrush doubles as a vibrator

recently I got a new toothbrush, its one of those that you see commercial for that have the spikes that move back and forth.  It a cheap crest jobby or something like that, i dont remember exactly what it is, but i'll figure it out and post a link.  so anyway, i'm pretty sure that this toothbrush could be turned around and used as a vibrator.  i recemmend you try and leave a crest toothbrush as a vibrator review here!
