Trailer time! Again. Here's another cut up creation culled from the many minutes that comprise our new flick Jackass Presents: Bad Grandpa, starring Johnny Knoxville and featuring Jackson Nicoll as his grandson Billy. It's got a ducky rocket, a fat penguin, and a deceased body that falls down and goes boom—all of which ultimately adds up to a resounding "Oh, my god." You can see this now, but look forward to seeing much more when it hits theaters like a solid case of the clap on October 25th!
