"B as in bandits. Who rob. And what do they rob you of? Logs. A blog is something that's contagious. It festers here and it eats away at the planet."

That's Amy Sedaris, explaining what blogs are. She's part of the new, six-part PBS documentary Make 'Em Laugh, which starts airing Wednesday night at 8pm (you can also buy the DVD in stores tomorrow). Amy not only explains the blogs, she also tells us what the internet is in general (like a big cave you drive out of). And "vlog" comes from the Latin for "head cheese."

This portion of the show is after the jump. Looks like PBS/WNET is going the VH-1 route and getting all hip with this documentary, having various experts on comedy sit off to the side of the screen, talking about comedy and making funny remarks, a la I Love The 80s or...well, 22 other shows.This looks like a fun documentary though. Besides Sedaris we'll hear from people like Dick Van Dyke, George Carlin, Carol Burnett, Chris Rock, Will Ferrell, Sid Caesar, Richard Belzer, Joan Rivers, Roseanne Barr, Billy Crystal, Michael McKean, and others. They're also going to feature many online humor, including College Humor, Funny Or Die, and zefrank.
