When "American Idol" inevitably returns, producers may want to consider recruiting Yvette Nicole Brown as a judge. The "Community" veteran may not be a recording star, but the enthusiasm she shows as host of "Cosplay Melee" would drive Simon Cowell insane. Other than her cheerleading spirit, this one-time special is just a low-rent version of "Face Off" with a measly $10,000 prize.

The tips on cooking, dressing and wooing are nice, but you'll spend most of the half-hour wondering how long before Penny has a sitcom of his own.
