While I agree with Eric's review of Beyond Re-Animator, I was suprised at no mention of the music video "Move Your Dead Bones" by Dr. Re-Animator. (Edit: He had a screener.)
It's easily the greatest thing to ever come out of the Re-Animator franchise. It's easily the greatest thing to ever come out of mankind in general. I play it on my radio show quite often, but I doubt too many get the reference.
