I didn't count all 1001, and they're not numbered, but a few are repeated.
The most interesting aspect is that the "laws" in question are given names; this is often the best part of the law, and often the most irritating.
The good ones are like this: "Utz's Second Law of Computer Programming: Any given program costs more and takes longer."
The bad ones are like this: "Keegan's Corollary: Many Irishmen grow grapes, for raisins of their own."
The worst one, which appears near the end (p. 170), is objectively false, and retroactively ruins the experience of reading the book, is: "Simmon's Law: The desire for racial integration increases with the square of the distance from the actual effect."
