Anyone got any good mnemonics?

[LauderSyme]

Yesterday I found myself telling ds the mnemonic I was taught when learning the order of sharps in musical key signatures: Father Christmas Goes Down An Escalator Backwards.

It prompted me to remember some others I learned, like Lefty Loosey, Righty Tighty, Stalactites Hold On Tight while Stalagmites Grow Tall With Might, and Some Men Hate Every One: Great Lakes Superior, Michigan, Huron, Erie and Ontario.

They must work cos I am well old now and clearly haven't forgotten! What mnemonics (useful or otherwise) are indelibly imprinted on your brain?

Cars are stationary
Envelopes are stationery

People have principles
Your principal is your pal

We did - Never Eat Cucumber, Eat Salmon Sandwiches And Remain Young!

Re the order of sharps- did you know that if you do the rhyme backwards it's the order of flats?

The music one that I remember the most is the order of key signatures. GooD AlE BeeF
Go from left to right and it's the order of sharp keys
G has one sharp
D has two sharps
A has three sharps etc

If you do the rhyme backwards ( putting a flat in front of all but F) it's the order of flats.
F has one flat
Bb has two flats etc

Very handy for music theory exams!

I can't remember the start of it, but chemical reactivity series finishes for me with 'I like huge copper mugs silently growing'

Also while it’s not a mnemonic I always use the knuckles trick for remembering which months have 31 days

I use 'righty tighty, lefty loosey' on an almost daily basis.

Can only remember the order of the balls in snooker by singing Chas n Daves'Snooker Loopy'
Pot the reds then screw back for the

Green
Brown
Blue
Pink
And Black

again not a Mnemonic but regular user of 30 days hath September, April, June, November' and then some nonsense about February.

Knuckles trick is amazing!
