I own four separate books full of Murphy's Law variations. It's a fun game to play.

Murphy's Law: Whatever can go wrong will go wrong.
Addendum: And at the worst possible time.

Corollary: If Murphy's Law can go wrong, it will.
Proof: Murphy's Law says that if you wash your car it will rain. The Corollary says that if you wash your car to make it rain, it won't work.

Murphy's Laws for the grocery store:
1. The line you are in is always the slowest.
2. Switching lines will make the one you entered slow down and the one you left speed up.
3. Switching back will make both lines stop and everyone mad at you.
