Things that only Japanese/ Chinese learners will understand

Sometimes the absurdity of the situation is too much not to laugh. I was thinking casually the other day, how many times a kanji mnemonic started with:
A woman was sitting on a stool..　
奴(やつ, guy)
Also...
致す (いたす)　means to do
倒す(たおす), however, means to overthrow.

If your leader tells you to do something, it usually means to overthrow the enemy.
Furthermore, who can forget the classic elephant / phenomenon 象　that once you add a person in there becomes a statue. 像

I'm sure that if all learners got together we could produce a bible of jokes inspired by the sheer absurdity of the Japanese language.
