Fingers, thumbs, toes, and sometimes back manually (Back being when I stretch after sitting hunched over a piece of paper because I dun wanna grow up all bent over XP), my wrists when they feel sort of... I dunno. Stiff-ish?

My ankles crack sometimes when I raise my toes too high o.o and sometimes when they too have the same stiff-ish feeling that I get with my wrists.

My foot cracks when I walk after a while, though I don't know why. It just cracks once, and it usually feels like bones moving back into place.

Aaaaaand... I think that's it. My left hand also seems to hurt more when I lift things, so maybe that's because of my cracking it...?
