Jackass: Bad Grandpa

Quick, cheap, dirty and raunchy: those are the key words to any "Jackass" production with Johnny Knoxville and the gang getting maximum, ball crushing bang for their limited bucks. They've been hugely successful too, with the entire trilogy of movies earning over $330 million worldwide, on very meagre budgets. Not bad. So of course the spinoff is here.

"Jackass Presents: Bad Grandpa" kind of came out of nowhere and is headed to theaters, this time boasting a "Borat"-esque concept. Knoxville's titular character embarks on a roadtrip with a kid, which gives the them all kinds of opportunity to reign havoc. And so this new red band trailer gets right to the good stuff (if you can call it that) with a penis gag, while three more clips extend the gags glimpsed at in the promos.

'Bad Grandpa' does bad things this Friday. Watch below.
