Webster's Dictionary defines "grand rounds" as nothing, because it's not even in there.Well done!
I was a little worried about what kind of posts people would submit, because I've observed some people have a questionable sense of humor. When I was in med school, I was an editor for our humor magazine and someone once submitted a copy of last year's physiology exam (although admittedly, that exam was pretty funny). Anyway, I shouldn't have worried. I think we have a good mix of the goofy, the twisted, the witty, the intellectual, and... the risque.
