This is kinda offtopic since it's english, but it's a kanji mnemonic and it made me laugh when I recalled it the other day so I suppose it's worth a mention:
位 rank
ONYOMI: I
as in, "Because of all the dick jokes in this book, I got the worst rank in the "nihongo textbook competition."
Btw is there a way to set up tatoeba plugin to show only japanese and english sentences? Sorry for double offtopic.
