David Tennant's face of the day

I actually saw this episode a week or so ago. John Simm as the Master in his insane, constant drumming, dancing phase was phenomenal in my opinion. I mean, six seasons of the new series later and I still think about him, and he was in wot, a total of 4 episodes, if that much?

That's some good acting.
