As the credits end, Rip mentions 'the next one should be The Son Of Jackass'. Fade to '2063: The Son Of Jackass', where an elderly version of the crew (as seen on Spike Jonez, Bam Margera, and Johnny Knoxville in the movie itself) attempts to escape explosions, flying debris, trucks, and crashing sheds. Only Steve O. makes it out alive.
At the end of the film, a warning appears. "Reminder: the stunts in this movie were performed by professionals, so for your safety and the protection of those around you, do not attempt any of the stunts you have just seen."
