Your Guess is as Good as Mine

In case you can't tell from the copious gray hair, I'm a bit too old for Arthur, and I guess my meme-fu is weak because I have no idea what the heck this is referring to. Hey, not every t-shirt you get out of a ShirtPunch grab bag can be a winner.

I mean, it'd be awesome if they made shirts about shows I remember, but I doubt there's a lot of demand out there for Mathnet t-shirts.
