Fans around the world flew to New York City to see Dan play the window washer-turned-business executive J. Pierrepont Finch eight times a week on Broadway in How to Succeed in Business Without Really Trying. And even though Dan tells J-14 Magazine exclusively that he's not really a good dancer, but that he just learned the moves and nailed it (we beg to differ!), he showed the world that there's a lot more to him than a wand and cloak.

So as a tribute, the fans put together this video to bid Dan, as well as his How to Succeed in Business Without Really Trying costar John Larroquette a fond farewell as they head into their final performances.

Glee's Darren Criss takes over the role from Dan starting January 3 -- and then Nick Jonas will follow starting January 24.
