Personally I don't find those parts that amazingly funny, I personally enjoy the more random bits of humor such as the bag, the fact they set up big cliff hangers at the end of some episodes just to solve them in the first minute the next episode. Kanako's random style of thinking. (Such as when the maid compared her too the Eiffel tower, I found her train of thought hiliarious. And the other completely random things that happen.
