he cracks his knees when he wakes up, but only after he cracks his neck. he cracks his fingers eventually when he's bored typing, much less frequently than he cracks his neck. he cracks his back by turning his upper body sideways, especially when he's about to fall asleep in the afternoons, after which he immediately cracks his neck.

he had a very rough night the other night, he didn't sleep at all, but every 10 minutes or so he cracked his neck.

he enjoyed sushi and his company last night, he liked the movie too, after which of course he cracked his neck.

life's full of shit, and he doesn't care; all he cares about is to crack his neck.
