One of the best episodes of "3rd Rock," beyond a shadow of a doubt, is "Frozen Dick"!
Though the snow thing is a mystery considering the time of year that this episode was released (though, I suppose, maybe not in Ohio), the aliens' first experience with it is one of their best discoveries ever. Dick gets himself and Mary thrown off a plane and then crashes their car into a snowbank. Harry suffers through the lack of customers at the video store. But to take the Kewpie doll, Sally, thinking the race has gone extinct and she and a visiting Leon are the last individuals on Earth, decides it is her duty to repopulate the planet. An episode full of hilarious gags, witty humor, and a classic reference to the only good part of "Twilight Zone: The Movie."
"'A lusty romp through the cheese and sausage shops of Communist East Berlin.'"
