Yet more reason for Yahtzee to be chagrined about the behavior of his fans [http://www.escapistmagazine.com/forums/read/7.124885].
He'd probably stick the gift in an obscure corner of the room and eye it with a combination of fascination and dread normally suited to some kind of forbidden Cthuluean idol, terrified by what it represents and yet too mystified by its very existence to discard it.
But perhaps I'm just being a part of the problem to assume I have any idea how he'd receive it.
That said, you should probably make it a gag gift, at best. Probably something you wouldn't be too offended to see chucked into a fire without a word. Any thought spared to, "I know what he really wants" would likely be interpreted as more baffling fan behavior.
