A late addition to the nativity scene:
Yeah, that's a spring-mounted Baby Jesus.
I have no clue where my mother found this, nor why it exists in the first place (is it supposed to be like a bobblehead? should I be mounting it to my dashboard?), but I guess if ever there was a nativity scene that could incorporate a spring-mounted Baby Jesus without anyone raising an eyebrow, it's probably mine. Welcome, boing-boing Jesus!
