They've had to cut way down on their on stage banter because they only get half an hour for warped. Watch the first DVD, or just listen to the full concert audio on spotify. One of the funniest things I've ever heard that wasn't a straight up comedy special.
Seriously though I can go for this, I hope they do a good balance of old stuff and keep the dirty work to a minimum but I'll buy just for the jokes and "behind the scenes" stuff during the feature. I still listen to the original concert on a weekly basis and have seen the DVD feature more than any other band DVD, and these guys aren't even in my top 10 bands.
