One of the great joys of YouTube is the proliferation of fantastically bizarre movie trailers from decades past; like buried treasure more and more are constantly unearthed, revealing a hidden past of movies that you probably never knew existed (and some that never should have.) The bloggers at PCL LinkDump have done some great work pulling several dozen of these beauties—from cheesy monster movies to the raunchiest sexploitation flicks—into one massive post. We would thank them personally, if we didn't have to devote the next several days to studying them all. As you can see from the sampling we pulled out after the jump, we may have a bit of a problem.
