i wish i could express just how much i disagree with your sentiment. i think it's a rather elegant attempt at conveying the humorous laws of reality in a classic cartoon existence. But hey, I guess not everyone can find it funny.

As I've first read Murphy's law and some other humorous "laws", there was an impression of the author making an insight and then formulating it in a minimalistic way typical for the real scientific laws, which is what makes the laws interesting and funny on two levels at once: there's an "a-ha" moment and the "similarity" to the "real" laws.

As I've seen enough cartoons, for me this list appears just to be a clumsy description of some gags. It fails on the appearance of insight and it fails on the appearance of the real-law minimalism. That's why it's not funny. YMMV, I see there are people who like it.
