"David?"

 I'm going to celebrate two people called David today, and one called John.

First, David Tennant, and part one of John Barrowman. The above video makes me laugh so much, and I keep watching it and watching it over and over... It makes me so happy.

Part 2! John Barrowman is NOT 50 like it was previously suggested, he is 45 and looking good, as I think you'll agree.

 Part 3, happy birthday to David Thewlis, who I idolise as an actor and a person. There's not reallya lot more I can say, really... Happy 49th, David!
