CKY is basically a bunch of videos created by Bam Margera, Brandon DiCamillo, and their crew from West Chester, PA. They named the videos after Jess Margera's band, CKY. These videos are pretty much an early version of Jackass.
The CKY series has four videos that show Margera, DiCamillo, their friends, and Margera's family doing crazy stuff, pranks, and gnarly skateboarding. They also added some original songs by the band CKY.
CKY
The first movie of the CKY series, titled "CKY," was released on March 1, 1999, by Landspeed.
The name Landspeed was inspired by Landspeed Wheels, a wheel company founded by Rob Erickson and distributed by Tod Swank through Tum Yeto Inc. They made skateboard wheels and clothes from 1998 to 2000.
The video is a mix of random homemade craziness and primarily focuses on stunts, pranks, and crazy behavior, as well as skateboarding.
The soundtrack features original tunes by the band CKY, including the famous song "96 Quite Bitter Beings."
CKY2K
CKY2K is the second movie from the series on May 22, 2000. It's got a trip to Iceland, some great music from CKY and other artists, and a skateboarding scene with songs from Believer and Aphex Twin. However, there was a scene that caused some trouble.
A young person exposed their privates in front of a public restaurant. Because of this, the video was discontinued due to copyright issues, with Björk being the first to raise objections.
CKY3
CKY3, released in 2001, caused a legal issue due to a fight scene. It was settled out of court in 2006. The video was taken off the market due to copyright violations.
Musicians were unhappy with Margera using their music without permission in CKY2K and the box set.
CKY4
The fourth and final film in the series was released on November 10, 2002. It had better editing techniques due to Bam Margera's newly acquired wealth and ability to purchase motion picture film cameras and use advanced post-production facilities. It included a lot of older video material, some unseen, some extended, and some off-cuts from previous CKY films.
Conclusion
It's possible that CKY, much like the last of the last of the Piss Drunx Dustin Dollin's view on skateboarding losing its edge, may not survive in today's generation.
