This is one of the more amusing Kanjis I've learnt.
As opposed to most Kanji, this one looks pretty much what it means!
Do you see the skewer in the Kanji?
Now another interesting one is this Kanji, which has the skewer Kanji as the top part of it.
Meaning: afflicted, disease, suffer from, be ill
Construction: skewer (串)＋heart (心)
"Doctor, I am suffering..."
