Movie and TV series Trivia game!

I will ask a deep philosophical question about a movie or TV series. The next poster can try to answer it be it factually accurate or merely speculation. Then he or she can ask an existential question he or she has been pondering about for years, months, days, and/or the 10 seconds it took to type it into the post. The next person will try to answer the question and then leave another query to continue blooming this intellectual forum into a film and TV trivia utopia! So on and so on.

Ready?

I'm wondering what was the first movie to depict a fart joke? Was it a silent film or a talkie? So... what was the first movie to depict a fart joke?
