Rhymes/Raps/Songs For Studying?

Pretty self explanatory. Was there any songs or mnemonic devices you used? Here's one of mine on the Proclamation Act of 1763.
The Proclamation Act Of 1763, the colonists were no longer free. Cant go past the west alps. 10,000 soilderss on the frontier, making sure no colonists were ever near.

Sometimes they can be pretty dumb, but hey, they work.

My science teacher last year had us listen to, memorize, and recite a song about scientists and atoms and stuff. It was torture, but the fun kind of torture that you get a thrill out of. The chorus went like:
Dalton, Thompson, Rutherford and Bohr
Schrodinger and Heisenberg and many, many more
Used their brains to venture through the world of interspace
To find the world of the atom is a weird and wondrous place

OH MY GOD my 7th grade science teacher was OBSESSED with this one. I hated it too. My parody was "Cells, cells, they're made of organelles! This song is awful, I'd rather burn in Hell!"
