The final trailer for 'Jackass Forever’ shows the men nutster than ever

The "Jackass" sequel is the fourth installment in the franchise. It began as a series on MTV. The trailer shows how the group has improved their skills with massive explosions, venomous serpents, punches and punches as well as bulls, bulls and treadmills.

Official synopsis: The movie celebrates the joy of being together with your best friend and a perfectly executed shot of the dingdong. "The original Jackass crew returns for another round hilarious, wildly absurd and sometimes dangerous displays of comedy with a little assistance from an exciting new cast. Jackass Forever sees Johnny and his team pushing the boundaries.

The group returned a large number of its members, with the exception of Ryan Dunn, who died in 2011, and Bam Margera (who had an argument with Knoxville).
