There are a few versions by now. Classic or “Matrix On-line” (the images work nicely) or classic with messed-up editing (stutter effect, imposed bits of speeded-up music).
Via Sullivan, the Schulz-as-Miller parody that’s going around.
Alan Moore’s Simpsons appearance; go to 6:24. Some joker taped the episode off his tv screen; the wobbly effect is actually kind of pleasant, but the sound suffers.
You know, I rolled my eyes at that pity party Moore appearance the first time it aired, but now? Ummmm.
