In this 1946 Soviet animation sequence, a miniature robot sailor prances on a piano with a human piano player. Everything's cute and wholesome...until the lil' mechanical Gene Kelly's skin begins to fall off. Then the weirdness begins.
I don't know where this clip is from (as my Cyrillic skills are nil), but it's plenty bizarre. Russian readers in the comments, feel free to chime in! Also, be sure to stick around until 1:29. That's when things take a turn for the Terry Gilliam.
