In a boost to a box-office that had been crawling along the past two weeks, Johnny Knoxville and co's Jackass: Number Two claims top spot at the box office, raking in an estimated $28.1 million dollars. Along with that haul will probably come numerous copycats, wannabees, and lawsuits. But if you can make a good living by taking shots to the crotch, then more power to you.

Other box office movements include Jet Li's Fearless and Flyboys debuting at numbers two and four, respectively, and the powerslide of The Black Dahlia from second place to sixth, ouch.

The Rock's Gridiron Gang continues to gain yardage, huddling up at the number three spot with a total box office of $27 million to-date, and Little Miss Sunshine is the little engine that could, hanging on to tenth place and crossing the $50 million mark.
