How to Enter a Clean Room

I kept picturing Woody Allen and Annie Hall like sneezing into the cocaine and blowing cocaine everywhere. I didn't want to contaminate it with my horrible American ways. So these are clean rooms. If we're breathing an infinite number of dust particles per cubic yard of air, it's about a hundred particles in this place. And they looked at me blankly because what they're worried about is like a particle of neon gas. Got to get there.
