I just came back from the dentist. Routine cleaning/check-up. Everything's fine in there.
My dentist happens to be a really hot woman (married, alas) and all her hygienists are also really hot. Walking in there reminds me of the purple-roofed ethical suicide parlor from the Kurt Vonnegut short story, "Welcome to the Monkey House" except instead of the hot women in their white clinical outfits putting you to death, they simply inflict pain and discomfort on your tender teeth and gums for a while after which you emerge with cleaner, smoother choppers. That metal claw? The suction tube? The rotary grit-scrubber? That ultrasonic torture needle? The stuff of nightmares! Except, wielded by a pretty girl, so how bad could it all be?
Personally, I think that instead of white lab coats it would be more appropriate if they were dressed in full-on dominatrix gear. More appropriate and hotter.
