Johnny Knoxville, who turned 55 this year, has finally called it quits on the "Jackass" franchise. Honestly, given the multitude of gnarly injuries he's suffered over the last few decades, he probably should've bowed out at least five years ago. Nevertheless, the release of this summer's "Jackass: Best and Last" felt bittersweet. Fortunately, we'll always be able to revisit the Jackass party, and that includes "Jackass: Best and Last." And as is often the case with these wildcats, there'll be additional footage that didn't make the final cut.
