I agree that memorizing the words rather than the mnemonics is both easier and more interesting.

But if you can only memorize two words, go for "za" and "qi" - they come in really handy to get rid of a q or z. (za is an absurd short form of pizza, and qi is Chinese life energy, same as chi.)

I also recommend the handy words qat (the stimulant leaf) and waqf (an Islamic charitable donation). After you're challenged unsuccessfully on waqf, you can get away with anything :-)
