Grammar Nazi Rides Again

I'm sure everybody's seen the commercials for Proactiv by now, if only because they're on about every twelve seconds on just about every channel there is. There's a part of the commercial where the spokesmodel satisfied customer is talking about how he uses the refining mask to zap sudden breakouts: "I put it on at night before I go to bed, and when I wake up in the morning, you don't have acne!"

That must be some pretty powerful stuff if he can put it on and cure my acne. Of course, that prompts the question, if I put on the refining mask, whose acne would I cure?
