Noone but New Yorkers will understand this - but in the scene where Jerry is trying to get the Maid to take his money on the street, when he is sitting in his car, the car's registration stickers on the windshield were taped on. Now why is this funny? It's a well-known fact in NY that the state DMV cannot make registration stickers that actually STICK to the windshield. You follow the directions, soak it in water, plop it on your windshield and the next day the sticker is lying on your dash. Everyone I know has their sticker taped to their window.
So kudos for slipping in a bit of fun at the expense of the New York State bureaucracy.
