YMMV / Mystery Science Theater 3000 S06 E11: Last Of The Wild Horses

• Bizarro Episode: Due to an ion storm and an atom transfer, Tom and Gypsy are sent into a Mirror Universe where Forrester and Frank are the guinea pigs and Mike and Crow are the evil scientists. Meanwhile, Tom and Gypsy's own evil counterparts are sent to the regular universe with the regular Mike and Crow (though evil Tom fits right in after noticing they've got a cowboy movie).
• Older Than They Think: Back when MST3K was on KTMA, Crow had a dream where he was in charge of the experiments with the Mads as his subjects.
