8. 'The Gang Makes 'Lethal Weapon 6'' (Season 9, Episode 9)
Back in Season Six, the episode "Dee Reynolds: Shaping America's Youth" featured a long sequence where Dee shows the gang's sloppy, possibly racist home-movie version of Lethal Weapon 5 to high-schoolers. Three years later, IASIP devoted an entire episode to the sequel of the sequel, seen in snippets as Mac and Dennis screen footage for potential investors. There's a high level of conceptual difficulty going on here, with viewers asked to imagine what was happening behind the scenes that made the finished film so cruddy. Some of it can be blamed on its creators' usual hang-ups — like Mac's inability to grasp why putting on blackface to imitate Danny Glover might be, you know, incredibly offensive. But mostly, it's exactly the nonsensical action picture you'd expect from a couple of dudes raised on Hollywood blockbusters.
