How many examples do you want? I have 9 books on the basic idea of Murphy's Laws....and one on Parkinson's Law.

My real treasure is a Murphy's Law calendar that I hung in an office where I worked. There was a big rainstorm...the roof leaked, and the water ran down the wall and ruined the wallboard, which allowed the nail to fall, dropping the Murphy's Law calendar onto a soggy carpet ans sticking the pages together.

One nice example: Rutherfords Rule: "The more you don't know how to do, the less you have to do."

and scary ones: McCarthy's Adage: "The only thing that saves us from the bureaucracy is inefficiency. An efficient bureaucracy in the greatest threat to liberty." (Eugene McCarthy)
