Watch a sneak peek from tonights “The Root of All Evil” from Comedy Central titled “American Idol vs. High School”. Both high school and American Idol feature harsh social criticisms, popularity contests, and shady characters – be it Ryan Seacrest, or the neighborhood creep. But which is more evil – calculus homework, or bad renditions of Aretha Franklin songs aired three times a week? To decide, Patton Oswalt and Andy Kindler go head to head in the court of the honorable judge Lewis Black, the ultimate evaluator of evil. Tune in tonight at 10:30 p.m. on Comedy Central.
