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

Denniston’s Law: Virtue is its own punishment.

Denniston’s Corollary: If you do something right once, someone will ask you to do it again.

Goofy guy’s observation of Denniston’s Law and Corollary: and again and again and again. This, however, is not reciprocated.
