I was a bit puzzled by Sam and Max-related comments about Max being a "gay icon," but then YouTube threw this at me and I've been quietly traumatised by the idea of either Sam or Max getting down to business since.
I'd always interpreted these as Max being indifferent towards anyone he wasn't pummelling or, in a universe that's rarely floated sexuality, asexual, but hey, when you put it like that: good for Max. And a point against my literary analysis skills. But I'll be looking for bunny ears at the next pride march.
