interesting

Literally never heard this. And I've been speaking Spanish most of my life.

how else will he know the proper way to hang the president

I've never liked right and left as labels for turning round things, because they have no top or bottom, and thus right and left are subjective. (And yes, i know that it's relative to the "top" of the screw relative to myself, but I suffer from left-right confusion and it's just not intuitive for me)
I prefer clockwise and counterclockwise. However, if pressed, i could be convinced to use Turnwise and Widdershins

  Same, but clockwise/counterclockwise doesn't help for me. And if I'm un/screwing something in a different orientation (like reaching behind the back of a cabinet) I'm extra-boned.
  Finding out that the right-hand rule applies to screws was game-changing. Make a thumbs up and align your right thumb with the direction you want the screw to go. Now turn in the direction your fingers are curling. Done.
  
  right hand rule
  Neat!
  My L/R confusion is specifically spacial, and includes East/West. Clockwise doesn't seem to be influenced in the same way for me. Probably something about the way my brain processes spacial direction. Anything other than top down is a struggle though. Bolts/screws behind or under something totally mess me up too.
  
  Right hand rule should be taught to every child. Fuck this whole "righty tighty" shit.
- Completely agree. Also, I'm a Spaniard and kind of a 'screw expert' and have heard the sentence in the post like twice in my life so not that common of a mnemonic. I usually say something like 'clockwise because time's tight' ('en el sentido de las agujas del reloj porque el tiempo aprieta').

Tell that to Robespierre.
- How? He was killed after his reign of terror. The left liberates.
