    To be really honest, a third column is missing with "untested". Sadly, that's undoubtably the largest column, and it would obscure the point of the comic as well.

    But the mouseover-text already makes that clear anyway …

    Ha-ha! I have three of his t-shirts. I love the battle-cry "Stand back! I'm going to try SCIENCE!!"

    Yeah, I love XKCD. It was the Bad Astronomer who turned me on to him, long, long ago.

    I was going to send this and then realized it would likely be here already.

    This is likely my favorite (tied with the one linked above):

    The number of people in the xkcd message board thread about this comic that are arguing for woo woo makes my head hurt :(

    I own 4 of his T-shirts (my favorite being "SCIENCE, it works bitches").

    I'm currently actually wearing the "my normal approach is useless here".

    I would link the shirts if his store hadn't been down for over a week now. I actually could have used the background radiation link from that first shirt for the discussion about the big bang with our new fundie friend.

    Woo in XKCD? Maybe I should pop on over and make a few comments in that thread.
