During the filming of the "Escape from Hellview" video, Chad Ginsburg almost hung himself while on a noose playing guitar to the playback system when he tried to flip his guitar. The crew and fellow band members thought he was acting, but when he started to spasm they brought him down.
During the filming of the video for "Sink Into The Underground", Jess Margera's father, who is heavy set, climbed an emergency ladder to see the view of the city, got stuck and delayed the filming.
The video for "Disengage The Simulator" was supposed to feature a man driving a truck off a cliff and into a quarry, matching what the song lyrics are about. The plan was that it would star Timothy Bottoms (one of Deron Miller's favorite actors) to be the unlucky truck driver that drives off the cliff. Every quarry that they asked to film there said no, and the only quarry that said they could film the video, only had a 10 foot drop. The band scrapped the idea and just had themselves perform in front of a big "CKY" instead.
In the video for "Frenetic Amnesic", The interior of the "Hospital" that they film the main character seek medical attention in was actually a gymnasium. That's why the hallways are so narrow.
