What was your mnemonic?

Had to use them all the time to get through flight school, but I can't remember those anymore.

The one I still remember from my 7th grade science teacher?

My very educated mother just served us nine pizzas ... to remember the planets.

 

Oh, and I can't remember which months have 30 days without using my knuckles. Everyone else uses the song, but I've stood my ground and just count knuckles.

 

Same with me with the planets. My third grade teacher taught us:

My very educated mother joyfully served us nine pickles.

 

"Homes" for the Great Lakes. Huron, Ontario, Michigan, Erie, Superior.

 

Whenever I go to a sushi place and see or here 'spicy tuna roll,' the words plague me to the tune of 'Just a Gigalo' for days on end.

It is not helpful in any way. It's agony, but it happens every time.

 

My 7th grade Spanish teacher had us sing a song regarding how to conjugate a verb. It was strange, but I still remember it 25 years later.

And, while not a mnemonic, I still do the "b" and "d" with my thumb/index/middle fingers at a restaurant to know which side is my drink and which side is the bread plate.

 

Shito, shitare, shiti, shictus?

 

Wonder what schoolkids use now that Pluto's been stricken from the list...

 

Every Good Boy Deserves Fudge (the lines on the staff in treble clef)

FACE (the spaces in treble clef)

 

Every Good Boy Does Fine
All Cows Eat Grass

 

For the bass clef, it's good boys do fine always and all cows eat grass.
On the treble, it's every good boy does fine and FACE.
