This whole thing is gay... But seriously, we're talking about Elementary...hell, I did my 4 year old sons V. Day cards and addressed them to boys and girl, and I've done my daughters cards too, and again, no big deal...Some people have way too much time on their hands...
I think the instructive thing about it is that, in today's climate, it is both absurd and believable.
