I get the Monty Python guys mixed up, too -- it's actually Terry Jones walking us through the history of inventions related to human sexuality. Sure, you could spend several days or weeks wandering through the internet picking up these bits and pieces of history -- but Terry Jones has already done the work for you -- and you can just sit back and enjoy his wonderful tour of how so many "modern" inventions were actually quite ancient.
I found this very entertaining and funny. Also very satisfying. Who would have thought that the Ancient Roman military had figured out universal fees for various sexual favors, and that the fees then were comparable to what fees are charged for those favors in modern times? Only, the Romans actually made tokens with the sexual act pictured on one side, and the rate paid on the other -- enabling their soldiers to communicate with Madams all over the Empire, even if the soldiers did not speak the local language. Brilliant! Now, how do you look THAT up on Wikipedia? :D
I believe that this is part of a series of films on "Ancient Inventions" by Terry Jones, formerly of Monty Python. Left me with a smile. I'd like to see the other films, too. :)
