If its all rigged with nice cortrol objects to make the animation easier then I would suggest that you think of what you want him to do then film yourself or a friend doing the actions, watch the video back noting down the timings of the different things (eg 1.13 - 1.15 turns head to look a glass, 1.16 - 1.18 reaches out with arm to pick it up etc etc) and animate it using this as reference that way your timings shoud be true to life. then with the basics down you can add your own "sparkle" to it.
