I've been a big fan of Dick Van Dyke for a long time, and it's great to see that he's still active and in the news! CNN has a nice interview with him in which he reminisces about making Mary Poppins -- and the hard time he has gotten ever since for his Cockney accent in the film.
If you want evidence that Van Dyke is still totally cool, though, you should watch Night at the Museum. Well, actually, just watch the credits. There's a scene where Van Dyke dances, and he had better moves at 81 than most of us have at 21!
