A short series on Comedy Central created by Matt Besser of the Upright Citizens Brigade – a parody of the utterly worthless "debate" form of "news" show. Crossballs would pair real experts with improv comedians taking the alternate position, and usually the experts wouldn't ever realize that they were being put on. (One example: I saw an ad placed by one of the experts that listed the various shows they'd been on, and after the usual suspects, included Crossballs. I'm not sure if this means they're that clueless, or if they're just counting on folks who'd book them not knowing what Crossballs was.) The series is best in small doses, although Comedy Central realized this, and only aired it 3 times a week, instead of their usual 20.
