We thought Gandalf the White was a bit of a stick. He was a military commander; he had to save Middle-earth. Gandalf the Grey was trying to do that, too, but he still had time to go party down in Hobbiton, smoke God knows what sort of weed with Bilbo, have a drink, play games with kids and let off fireworks. And we get to see a little bit of that in The Hobbit.
