X-ray vision

This may surprise you, but I have x-ray vision.  It may also surprise you that I have psychic powers.  It came as a surprise to Jakub this morning as well. 

Jakub had just walked into the room first thing in the morning:

Me: "Good morning, honey."
Jakub: "Ergh"
Me: "Are you wearing underwear?" (he has been refusing to wear underwear lately when he dresses himself in the morning)
Jakub, grabbing his backside with baffled expression: "But you can't see!"
Me: "Yes, I can.  You're not wearing underwear."
Jakub: "But today's Saturday, there's no school."
Me: "So if there's no school, you don't have to wear underwear?"
Jakub: "Yes."

Hey, at 5:30 a.m., that seemed like sound enough logic to me.
