If you're building a parody film using a very serious movie for your video and Yakkity Sax for your audio, there are certain guidelines that must be followed.
1. The speed of the film must be at least 50% higher than normal. 100% more is preferred.
2. It can't just be any footage. A Benny Hill parody is, by necessity, all about the chase.
3. Part of the visual humor is that bipedal locomotion, whether walking or running, is extremely funny to look at when sped up. So try to stick with bipedal locomotion (as opposed to quadrupedal or vehicular locomotion).
4. Scantily clad women are a bonus, but not necessary. If they don't fit into the chase, leave 'em out.
That is all.
