Smut Cliché: Nurses are sexy

Why it should be changed: Nurses selflessly care for the sick and are an invaluable part of the healthcare industry. But sexy? No. These are professionals who regularly give enemas and slide catheters into itty-bitty bodily orifices. There is nothing sexy about having your bedpan changed.

Alternative: Sexy ninjas, since they can appear and disappear in puffs of smoke.
