Yes, he's obsessed with Pixar movies. Can you tell?
Now this part is totally my fault. He was sitting next to me, and I didn't notice that he was being quiet, partially because I was tired, and partially because I was watching Battle of the Network Stars. I love my video collection sometimes.
I turned to say something to him when I saw that he had a pen in his hand.
"Brody Alexander!"
"No, I'm Double Boy."
"Huh?"
"Double Boy." He held out his arm. "See? W-W-W..."
Sure enough, for some reason, my son decided he'd be a walking billboard for THX by writing www.thx.com on his left arm.

"Oh boy," I said. "Go show your mom why you're Double Boy."
As he hopped off the chair, I noticed he gave himself stylized kneecap tattoos as well.

Moral of the story: Beware of quiet kids. They're up to something.
