I thought that "The Saga Begins" worked really well in The Ridiculous Menace, and would love to see Weird Al songs incorporated into the next two edits, too. Some ideas:
-"I Think I'm a Clone Now," track 5 on Even Worse. Could work well when Obi-Wan is being given a tour of the Kaminoan's cloning facility.
-"Slime Creatures from Outer Space," track 7 on Dare to be Stupid. Might be amusing over any of the scenes featuring battle with the Geonosians.
-"Yoda," track 5 on Dare to be Stupid. Might go well either with Yoda's duel in this movie, or in the next.
-"Fun Zone," track 11 on UHF Motion Picture Soundtrack. Just a nice peppy, up-beat, kinda silly, instrumental piece that might work well in any number of scenes.
