After rancorous debate, Pluto, it is agreed, is no longer a planet. That's too bad for those mnemonics users. I haven't had to use mnemonics for remembering the planets. I just do. It's probably because I was deaf, and the only way I could take up words were not to repossess them in other words, but to memorize them myself. The same goes with all the colors of the rainbow.

So far, I did use mnemonics for remembering the animal kingdoms: King Philips Coughs Out Freaky Green Stuff.
