Duck Soup (1933)

My introduction to the Marx Brothers was a learning experience. First, I learned that Alan Alda pawned his character Hawkeye from MASH completely from Groucho. Second, I learned how annoying Harpo is. Thirdly, I don't think I have ever seen a film before that packs as many jokes-per-minute as this does. They fly so thick and fast that its actually astounding that they managed to squeeze a story into the mix: bare bones, every second of it, and there just to drape jokes over. But you couldn't ask for anything more from a comedy than literally non-stop laughs.
