Great read on the comedy gold that was Mr.Show.  Here’s a snip:

BRIAN POSEHN (writer, cast member): You’d have to walk through some crazy disco to get to the stage. That whole place had a weird vibe. Super-cokey — and that was in the early ’90s when coke was out. Bob and David were doing this thing called the Three Goofballz.

RATH: It was the two of them, but there were three big refrigerator boxes onstage. They did this goofy song about how they were the Three Goofballz, and then David popped out of one box and Bob popped out of another, and then the last box, nothing happened. They were like, “What’s going on?” They stopped the show, and they’d had one of the older comedians, Jeremy Kramer, play it like he’d had a heart attack and died in the box.

POSEHN: They had different people who’d be the third Goofball. I did one episode where I played their third partner, and I was not even there. They opened up the box and on video I’m getting high with a bunch of grunge kids.

SCOTT AUKERMAN (writer, cast member): I had never seen comedy like that. Just how much they cursed. And how inventively. I’ve never seen people who were so unafraid to take the kind of risks they were taking.

MAYNARD JAMES KEENAN (musical collaborator, guest star): There might be 40 people there, 15 of them are performing. Afterwards, you headed to the bar and there’d be a herd of funny.
