Your useful mnemonic devices

A very nice pic. Consider it snagged.

I especially loved "Microsoft Made No Profits From Anybody's Zunes, Yo."

I do have to nitpick the Order of Operations: doesn't Division come before Multiplication? If so, may I suggest the alternative: "Please Email Dr. Mengele A Shark?"

Division and multiplication are equals. But I'm not XKCD, so don't think that was mine...I'm going to edit in a proper link to the comic....

never eat soggy waffles - north east south west
please excuse my dear aunt sally - ()^*/+- order of operations
every good boy deserves fudge - EGBDF musical notes
dumb kids playing catch on freeway get squashed - domain, kingdom, phylum, class, order, family, genus, species

These are the only ones I still use, I'm sure there are others I knew but have forgotten.

ROY G BIV - Colors of the Rainbow
Neg Exo - Exothermic Reaction
Left hand makes a L

I have a lot more but I'm seriously drawing a blank right now.

Hm. I guess I don't use any. I just remember stuff. They are useful though, perhaps I should start using them more often.

kind of like Every Good Boy Does Fine. I got that from my guitar teacher, for reading sheet music. Nah, it didn't work.

Yeah, I used one that went 'Every Good Boy Deserves Fun'. Thing is, I've totally forgotten what it was for

I remember it as Every Good Boy Deserves Favour.

And there is also FACE.

The empty spaces between the lines in ascending order are F A C E which can easily be remembered since they spell the word "FACE". So if you put them together you get E F G A B C D E for the notes on the treble clef.
