I caught The Nativity Story Monday evening, and one of Joseph’s lines (“I wonder if there’s even anything I’ll be able to teach him”) got me thinking about the parts of Jesus’ life that we always read and hear about, and see on screen — and those we don’t. What about Jesus’ awkward pubescence, for instance? Is there a great comedy (or, OK, more likely mediocre comedy born of a great concept) that I don’t know about? Hell, you know, I’d even I’d even settle for a Gospel-style Muppet Babies, with Jesus and his little cousin John the Baptist navigating the “terrible twos.” Who’s with me?
