Any episode of Monty Python will reduce one to fits of laughing that will produce bouts of tears that will render the viewer on the ground. Great physical comedy on all parts, but especially John Cleese in the Ministry of Silly Walks sketch, which is his least favorite sketch. Great writing that walks that fine line between genius and silly, and meshes the two. These guys also knew when and how to start end a sketch. Still funny thirty years later, wish the same could be said about Saturday Night Live. Too bad there wasn't some knight who could hit Lorne Michaels with a chicken.
