A roller-derby star does a commercial for a breakfast cereal; the whole idea is so wholesomely retro it really ought to be in black & white.

I had no idea, until seeing this commercial, that there was a roller-derby league centered in Manhattan. I went online to see when the next match was; turns out it’s Saturday night at the Hunter College gym. Tickets, unfortunately, are sold out. You read that correctly: The Saturday-night roller-derby match is sold out, in 2010, on the Upper East Side. The limits of the possible are changing in this country, continually, and not just in politics. If you stop and think about it, every day should be the Fourth of July.
