It's Garry Shandling's Show.

I watched this in Britain in the late eighties/early nineties, and though it was relegated to the graveyard slot on a minor channel it still has a mass fan base who would love to buy it on DVD, even Region 1. But there's no sign of it being released! Why is this? If anyone associated with the relevant network reads this please consider releasing it. You may find that very soon someone will 'borrow' the idea, have a massive success with it, and the new version will be considered more successful, and the show will simply be relegated to history. The time is ripe for a Garry Shandling revival! Who's with me!!
