Xenocide I'm pretty sure this is a dupe. BUT IT'S THE GREATEST DUPE EVER.
In fact, this site could just be dupes of this video and I would still five them all.
Aelric I didn't find it under Hitler, so if it is a dupe, it needed WAY better tags
Chalkdust it was included in a compilation of similar "what" moments from MST3k but is clipped shorter
Syd Midnight It was my submission, "Top 10 Mike-Era WTF Moments". This was #1. So it's not really a dupe and deserves your stars.
Camonk This video says a lot of things about Japan.
As usual, none of those things is good.
BHWW The uncut version of "Neptune Men" apparently featured a lot more actual footage taken from WWII bombing raids, including footage from an A-Bomb detonation and the MST3K crew was somewhat appalled. As Kevin Murphy put it: "To glibly summon the darkest shadows of our century because one has run out of models to blow up is to stoop to Schumacherian levels of banality."
