The Barbarians (1987)
starring the Barbarian Brothers (Peter and David Paul)
This is a movie that needs mocking. The Paul brothers play the two dumbest slabs of greased meat in mullets ever to emerge from the age of sword'n'sorcery flicks. If you ever wondered why the dark ages lasted so long, it was because oafs like these were doing so much to hold back the Renaissance. It makes you run screaming to a screening of "Red Sonja", just for some more intellectually rigorous storytelling. And better dialogue.
They actually thought that doing seal impressions was so funny, they repeated it at different times in the plot. Yes, apparently, that was their input into the movie, which they came up with when combining both their brain cells.
