A babushka is a Russian grandma, the kind who hobbles around in cloppy shoes and wears a scarf over her head.
So Day doesn't remotely look like one, but I think the scarf makes him look as feminine as he'd ever be. And rather sweet, eyes downcast and all.
Yup, I was in another one of my I-can-do-anything-to-him-since-he's-my-son moods. It's great having a living doll.
