Oh my God they didn’t.

Yes, they did.

This is a real, working Wi-Fi detector on the front of this tee shirt.

From ThinkGeek, masters of this kind of brainiac fun, you can get this for less than $30 and be the King Hell Ubergeek of the party. But, only if there’s Wi-Fi around.  Which, if you are a King Hell Ubergeek, there will be. Or you wouldn’t be there.
