Riding on the wave of the toilet flush...
Nuke those toothbrush germs!

I wish I could link to individual comments directly; instead, let's try this:

#4: The first voice of dissent.
#6: What do I do with an electric toothbrush?
#11: What do I do without a microwave? Provide alternative plz.
#12: Why would they provide an alternative?
#14: I'm a dentist and I approve of this message.
#17: Remove the battery from your electric toothbrush, DUH.
#26: I'M A DENTIST AND I DISAPPROVE OF THIS MESSAGE.
#51: My battery is sealed in, dumbass.
#57: The First Ammendment says you have to provide the alternative!
#64: This is as stupid as Obama's tax plan.
#69: Enter citations!
#71: Winner.

And then it gets better: it's a government plot, it's the fault of CHINA, inexplicable invocation of Dick Cheney, let me show off the brand of my toothbrush! 110 comments and counting. [ETA: Bizarre science at #121!]
