While it's certainly been rearing its head with increasing regularity - Dave Egger's themed storefront on Valencia, various jokes on Late Night with Conan O'Brien, and, as recently as today, a short piece on the McSweeney's web site - it hasn't been officially stated yet, so please allow me. In the world of comedy writing, PIRATES ARE THE NEW ROBOT. (as you'll recall from several years ago, robots were the new monkey.) As you were.
P.S. I'm still waiting patiently for mummies to become the new pirate / bigfoot / hobo / what have you. Mummies - our day will come.
