- Author Existence Failure:
- Ryan Dunn died in a car accident in 2011.
- Averted in Johnny Knoxville's case, THRICE, first during the "Rent-A-Car Crash-Up Derby" in the first movie, where one of the cars crashed into his, having its wheel smash through the windshield, inches away from Knoxville's face. The second was during the "Golf Cart Antics" in the same movie, where the golf cart with Knoxville and Dunn (who was driving) flipped over a fiberglass statue and got wrecked. Knoxville actually could have broken his neck from it. The third was in Number Two in the "Big Red Rocket" skit, the rocket he was gonna fly up into the air and into a lake ended up misfiring, exploding with him on it. It exploded on one part just inches away from his stomach. Then he tried it again, that time it worked.
- Creator Breakdown: Bam has NOT had a good few years since Ryan died. Thankfully he stopped heavily drinking in 2015, though it was another 2 years until he could skate again due to joint problems caused by years of stunts, and the weight gain caused by not walking much during this time. That said, he's still not mentally well and even left rehab in 2018.
- Development Hell: Plans for Jackass 4: We're Not Dunn Yet were announced, but so far only Knoxville, Tremaine, Margera (who coined the title) and Steve-O have shown interest; the latter, on the condition that Bam would remain sober enough for filming the said movie.
- Executive Meddling: Among other things: after season one MTV handed Knoxville and company a list of things that they were not allowed to do, as far as content goes. Similarly, when Sen. Joseph Lieberman tried to get the show banned from airing, MTV caved like cowards, pulling all reruns of the series (which was in season two by that point) and forcing Knoxville to revise the show's warning so as to read it out loud to viewers.
- Lieberman's actions also squashed plans for a "Jackass: Too Hot For TV" video release.
- Follow the Leader: Jackass spawned many shows in the same vein, including Crazy Monkey, and Rad Girls. Sometimes, MTV itself did this (with Dirty Sanchez and Rob Drydek's Ridiculousness). Ironically, Jackass itself is derived at least in part by SuperDave Osborne, a parody of daredevil stuntmen like Evel Kneivel, played by comedian Bob Einstein. Einstein himself doesn't like the comparison, pointing out in this interview that his antics as Super Dave were almost impossible to emulate.
- Foreign Remake: Jackass inspired French humorist Michael Youn and his gang and the result was the 2004 movie The 11 Commandments.
- Keep Circulating the Tapes: The only full, uncut episode available on DVD is the hour long Gumball Rally episode, which is only available on the bonus disc for a box set released. All three seasons are only available as a series of "Best Of..." compilations (with V2 and V3 having two releases, with the re-release having extra sketches added) and a "Lost Tape" compilation, which has all of the opening/ending sequences and the MIA sketches that didn't make the previous three DVDs.
- Further adding to the mix, the season one "best of..." set was delayed for about 6 years due to feuding between the Jackass crew and MTV; while Knoxville and company have full control over content for the DVD releases, MTV outright refused to let them release season one on DVD due to their not wanting to let the gang wanting to release the Big Brother magazine sketches uncensored. Knoxville and company finally caved, meaning that you'll have to track down the original Big Brother magazine VHS tapes for the full version of the self-defense test sketch.
- What Could Have Been: MTV (who owns the rights to the name "Jackass") seriously considered making a Season 4 with all-new cast members and even put out a teaser commercial in the 2002 VMA Awards. Thankfully they didn't when reaction to the news was extremely negative.
- Jackass: Too Hot For TV, which got killed when Lieberman started making noise against the show.
- Bam's uncle was to be in Jackass 2 a great deal (you can see the original Lambo-tooth-pull in the trailer used against him), but a judge ordered all scenes relevant to him pulled off after being convicted of child molestation.
- The Terror Taxi very nearly got here they nearly got stopped by police twice, and Jay Chandrasekhar kept going off the rails (the police were told about the skit, but they still set up a damn roadblock), and two bystanders called the cops.
- They were also about to attach squibs to the fake dynamite to scare Ehren more, but the Fire Marshall told them they had to more or less ruin the prank.
