A more risky bit of trivia… In the election of 1860, there were five states in which Lincoln got ZERO votes. Not so much as a prank!
I learned the 12 cranial nerves using a different (x rated) mnemonic.
The sentence “Old maids never wed and have babies” is a mnemonic for the first seven railway stations on the Main Line west of Philadelphia - Overbrook, Merion, Narberth, Wynnewood, Ardmore, Haverford and Bryn Mawr.
Amazingly enough, that line came from my TV as I was reading this thread. (Austin Powers: Goldmember, which my TiVo recorded last night.)
