Courtesy of Gay Gamer, this darling cross-stitch of an incestuous Mario & Luigi, holding hands right before Mario sends a mushroom down Luigi's pipe and they both hold a cute post-coital cuddling session.

Well, okay. It's not quite so blatant. I'm an only child, so I don't really know if brothers wander around holding hands with a beating, disembodied hovering between them. Possibly!

If it's incestuous, it could still be more disturbing: this could be Baby Mario & Luigi we're talking about here.
