Another great example of working within a pose from Fargo. When the guy talking mentions "Mrs Mora" he gestures behind him with his thumb out. Watch how long he stays within this pose. If one was animating this line, it would have been very tempting to have him make more gestures after this. When creating your keys, try a pass with as few as possible and see if you can make it work.
