The original anarchists.

I used to keep a copy of "Duck Soup" in my office, and would show selected scenes to subordinates when the pressure got too high. Our favorite scenes were:
--Chico and Harpo reporting to Louis Calhern about their tailing of Firefly ("Then you didn't shadow Firefly?" "Oh sure, we shadow him all day." "What day was that?" "Shadowday...ha, ha, at'sa good one, eh, Boss?") Calhern made a great straight man.
--Groucho's introduction to Margaret DuMont ("I held him in my arms and kissed him." "Oh, so it was murder?"). One of Groucho's biographers said the reason DuMont always looked so absolutely perplexed was that she really didn't get it.
--Edgar (The Slow Burn) Kennedy harrassed by Harpo and Chico.
