He: What's your favorite planet?
She: Pluto
He: Pluto's not a planet anymore.
She: The moon
He: The moon's not a planet either.
She: Earth?
He: Huh, well my favorite is Venus. And Jupiter. And Mars. I like all of the planets.
She: Oh yeah, me too...
I dunno, but somehow I don't think that I knew that many planets at 3 & 5...
