I can't forget the Quadratic formula. That thing has been burned into my mind with that catchy song.

I never forget the first 10 elements of the periodic table.

I can't forget the order of the planets from the sun from this silly mnemonic device I made up when I was 10... xD It was "My very energetic マウス jumps n' sings under no pillow" o.O

very (venus)
energetic (earth)
マウス (mars)
jumps (jupiter)
n'
sings (saturn)
under (uranus)
