No movie I have ever seen makes me laugh harder or more consistently than Holy Grail. And that's after seeing it enough times that I've become one of the annoying legion who can quote entire scenes from the film. Python are a rare combination of physical, low brow, silly, and philosophical humor. Some scenes you laugh at because they are so stupid (killer rabbit), others because they are so absurd (Black Knight) and others because of the amazing language used (anarchosyndicalist commune).
