After going through the backscatter x-ray at the airport the screener made small talk: "you work at Google?" I'm puzzled, and it shows in my voice when I say "yes". They say they read my shirt. I smile, and move on. A minute later I realize that I'm wearing another shirt over my (new) Google shirt. That is the point of these machines, I guess, to see through clothing.

Which makes me wonder: what if someone made some shirts that looked completely normal but had some fibers opaque to x-rays, writing out an insult to the TSA? Perhaps a white t-shirt saying "replace the TSA" in black pigment but "@#$% the TSA" in metallic fibers?

(I don't actually dislike the TSA, really. I just think they're ineffective, especially considering the amount of money they spend and passenger time they waste. And Blogger Bob is beyond dumb.)
