Weird, I had to check Imdb. I've never seen the 'get on with it' scene.
I saw this in theaters around 1996 or so, and have 2(?) different DVD releases and it was news to me.
I didn't realize they kept messing with the cut of this film.
The extended Anthrax scene was on Comedy Central's broadcast the first time I saw it, then the 1996 theatrical re-release and the 2001 2-disc Special Edition. I'm pretty sure it wasn't an original theatrical scene.
I'm confused, isn't the original 2000 DVD release what you're looking for?
