BUT, you left out the best episode. SPACE MUTINY!!!!
I have watched that one probably 100 times, and still laugh my a$$ off every time.
SM is followed by Manos (Worst. Movie. Ever.), Eegah, Violent Years (what a horrible way to die), Girl in the Gold Boots (One line makes me fall out of my chair laughing - "Whoop, I'm BACK!"), Hobgoblins, Santa vs. The Martians, Ator, Hercules (any of them), The Day the Earth Froze ("Bring me a SAMPO!"), Outlaw (Oh, it's breasticaboobicle chesticamammicle, areological fun!), etc, etc, I could go on all night...
If you guys haven't seen Space Mutiny, GET IT. It is seriously the best MST3K episode. I barely survived watching it the first time.
Also, if you are interested, Mike and the guys that played Tom and Crow are doing their own thing now called Rifftrax. Check them out at rifftrax.com. I have seen a few of those, and they are still hilarious. They charge like 3-5 bucks for an mp3 of the riff that they do, you just need to sync it up with a dvd. Oh, and these are mostly modern (and usually pretty good) movies. I am watching their riff on Star Trek (the new one) this weekend.
Joel and Trace (Dr. Forester) are doing their own thing, too, but it isn't as good.
Oh, and I am following 4 people on Twitter. One of them is Mike. It was 5 until a few minutes ago. I had to unfollow Adam Savage from Mythbusters. He keeps spouting liberal crap. Seems he is really happy about ACORN investigating itself and finding no illegal activity. Oh, brother...
I hadn't seen that one in years, and I've watched it twice in the last week. It is absolutely hilarious! That midget with the obnoxious voice that Crow perfectly imitates, the host segment with the book "Palance on Palance: Believe It or Not!" (ex: "Day 1: missed call; partied all night with that blonde midget fellow"), and of course the musical portion you referenced. Definitely a classic episode!
I will break with most here and say that "Manos" was far too tedious to be the best (worst?) MST3K movie done. If you as the viewer have to slog through it as well, it just isn't fun ("The Screaming Skull" is another, as is "Invasion of the Neptune Men"--pure pain, not a single fun thing about them). That's why I like "Hobgoblins" and "Deathstalker"--ambitiously bad, poorly conceived, terribly executed, insulting, with plenty of fodder for fun skewering. You come away with a feeling that you have watched an AWFUL movie, but you don't feel tired by it at the end.
