Beware the Nice Ones/Music

• The Gorillaz cast all have their moments, excluding resident Jerkass Murdoc. Noodle once fought off an entire zombie army alone with nothing but her Waif Fu, and the usually cool-headed Only Sane Man Russel knocked Murdoc out cold with one blow when he tried to kill 2D. Even Extreme Doormat 2D has a limit: he lashed out at Murdoc in a recent interview after a few minutes of insult and humiliation.
• Kenny Rogers' classic "Coward of the County". A man who'd turned his back on fighting all his life beats three men to a pulp after they rape his wife.
• Lemon Demon's "Ultimate Showdown of Ultimate Destiny" brings together absolutely everyone in a Battle Royale With Cheese, from Batman to Godzilla to Chuck Norris. The winner? Mr. Rogers in a bloodstained sweater.

Class? "SHUDD-UUUUUUUUUUUUUUUP!!!!!!!!").
