There seems to be an ongoing rivalry between the MD students and EVERYONE else (but especially dental) at our school. I don't think anyone in our class really gives a crap, but I have heard several snide comments from "other" students as I've walked through the halls (in plain cloths...we all have different colored scrubs, so it's usually easy to spot MD vs dental vs nursing vs pharmacy, etc)
I overheard one guy complaining that our med-ed office kicked HIS class out of a lab so the "damn medical students could use it"...which was followed by "you know those guys OWN this school". Needless to say, I just put my head down and kept walkin' !
