Electronics/Laser mnemonics you remember

OK,
Do you have any electronics or laser related mnemonics that you remember from school?

The only 2 I can recall off the top of my head are....

Bad Boys Rape Our Young Girls But Violet Gives Willingly. Get Some Now!
Resistor color code.


ELI the ICE man
voltage(E) leads current(I) in an inductive circuit.
&
current(I) leads voltage(E) in a capacitive circuit.

**I added Laser to the subject because I remembered another one.**

Roy G. Biv
Red, Orange, Yellow, Green, Blue, Indigo, Violet
The rainbow spectrum.

So long as we're willing to digress from electronics, I recall my college astronomy class mnemonic for steller classes, in order:

Oh, Be A Fine Girl, Kiss Me (Right Now). :evil:
