From my “Murphy’s Law” desk calendar archives thanks to Aunt Evelyn, Uncle Pipey, and cousin Nancy:

Freeman’s Rule: Circumstances can force a generalized incompetent to become competent, at least in a specialized field.

Goofy guy’s advisement on Freeman’s Rule: i have met many such “competent people” over the course of my careers; sadly, their number seems to be growing, and they all seem to think their “competence” in one area makes them omniscient in everything .
