missing from the DVD:
The Season 4 Blooper Reel
4 Season 4 TV Spots that weren't on the other DVDs
The Best of Season 2 (They put the best of season 1 & 3 on the other dvds, and the season 2 one is missing).
It seemed like they had it all worked out with how they were going to distribute the TV spots and best-of specials, and they even referenced that they'd be putting the season 4 blooper reel on the DVD, but they fucked it all up on this set
And the Naked Improv sketch from Comic Releif is butchered, they cut a bunch of stuff out and it sucks now.
The Mr. Show Jukebox thing is fantastic, but I'm sad they couldn't include the "Mr. Show Movie" song from the end of Run Ronnie Run (you can't even hear it because Troy Miller put it in the background of the Jackie Chan sequence because he's a fucking moron asshole idiot jerk). I'm assuming they couldn't get it from New Line or didn't even try.
But the reason to buy Mr. Show DVDs are for the commentary. Jay and Paul's voice over thing made me laugh so hard I felt sick.
It just sucks that they left out so much that should have been obvious
