One ironic thing that I notice about male nurses is that they are soooooo often mistaken for doctors. On the flip side, female doctors are often mistaken for nurses.
My mom's had a few young male nurses and she calls them "Doctor Adam" and "Doctor Steve". She says she knows they're not doctors, but she just likes to call them that anyway. They don't seem to mind....
Oh... and how about theONE and AY. I think they'd make fabulous attention-getters. I came up with that on my own, ya know.
