"Jesus is like a basilisk person."
Torn about explaining or not, but because I probably won't remember for more than an hour, I will (despite the fact that I think it's more effective on its own). We were in the car, and minds will wander. He's been watching educational TV about animals and is fascinated by the basilisk, a lizard that's able to skim/run across water. Then his mind was wandering about God and Jesus, and how you can't see them, but you can talk to them anytime you want to. Then, out popped the gem.
