From my “Murphy’s Law” desk calendar archives thanks to Aunt Evelyn, Uncle Pipey, and cousin Nancy:
Willoughbby’s Law: When you try to prove someone that a machine won’t work, it will.
Goofy guy’s realization of Willoughby’s Law: When i began mowing our neighbors’ yards as well as our own at nine years old, i would often flood the mower engine because of inappropriate use of the choke. i never get it started and would have to call my father who would drive home from work, take one pull on the engine cord, and the mower would start. This was repeated several times every summer until i was about 14 (Joe, when did you take over the mowing jobs?). i finally realized Willoughby’s Law was indisputable.
