Giant bug intrudes on Howard Dean MSNBC interview

Former Democratic National Committee Chairman and one-time presidential hopeful Howard Dean was upstaged by what appears to be a huge bug crawling across the screen during an interview on MSNBC's Dr. Nancy show.

"Politicians at the federal level who are talking about tort reform are just blathering," Dean says before the creature makes its cable network debut. YouTube user "jeffmaxweed" uploaded the video to the site, and Raw Story has confirmed it did air Friday.

One possible explanation is that the bug crawled across the lens of a backstage projector while cameras were rolling.
