He's a brainiac, brainiac . . . on the floor.

And he'll work that brainiac right out that door . . . .

My apologies to "Flashdance" but it's the best reference I could come up with on the fly. A cute/brilliant moment happened a couple of days ago:

Bennett is playing with two measuring spoons as Brian and I are getting ready for the day. We're all in the kitchen.

Brian: "Bennett, which one is big?"
Bennett: (thinks for two seconds, holds up spoon in his left hand - 1 tablespoon)
Brian: "Bennett, which one is tiny?"
Bennett: (thinks for one nanosecond, holds up spoon in his right hand - 1/4 teaspoon)
Brian: (turns to me) "I think we've got our hands full, honey." *Grins*

p.s. Bennett hasn't been wrong since.
