Space Ghost Coast to Coast (1994)

The show Adult Swim grew out of. It started on Cartoon Network in 1994 and moved to the new late-night block in 2001: a talk show where a recast 1960s superhero interviews real celebrities on a monitor, usually assuming they are fellow heroes, while his old enemies Zorak and Moltar work for him as unpaid punishment. Stitched together from reused Hanna-Barbera animation, it set the cheap, non-sequitur rhythm much of the block followed. Episodes run 11 to 23 minutes. Baffling level: medium, mostly because the interviews go nowhere on purpose.
