You know, there's a bit of truth in this that got a chuckle out of me.

Anyway, I'm a bit impressed that you animated the character rotating in that office chair. Also, as far as tween/modular animation goes, this is not bad. Still, I think you can improve this kind of animation. Try having him move subtly (i.e. breathing) when he's more or less still and apply anticipation to his actions. Even something like a slight lift of the arm needs to have it lightly nudge slightly in the opposite direction prior to the intended action. Also, have you considered applying a little more weight to your animation?
