Weebl and Bob (found DVD exclusive episodes of web series; early 2000s)
From The Lost Media Wiki
The animated web show "Weebl and Bob" was created by Jonti Picking and Chris Vick, and it had several episodes that were exclusive to MTV or DVD. The MTV-exclusive episodes included "trailer," "hostage," "sex 1," "sex 2," and "sex 3"; and the DVD-exclusive episode was titled "pipe." Additional episodes, including (but possibly not limited to) "thirty" and several episodes from the show's 2004 Advent Calendar, all appear to be unavailable as well.
The "trailer" episode can be found here: http://web.archive.org/web/20040530123435/http://www.weebls-stuff.com/testy/trailer2.swf, but the rest of the episodes have not yet been found.
