Make sure you watch it until the end.
On the subject of dancing awesomeness... My two favorite dances of all time are the Charleston and the Jitterbug, neither of which I know how to dance. No matter how much I practice the Charleston I simply can't get my foot to twist pigeon-toed and go behind and then in front--I need my brain to shut down because it perceives this move as unnatural and I simply can't do it! Maybe the secret is drinking a few French 75s and dressing like a flapper, a theory I have yet to test.
My other favorite dance and favorite version (because it is from I Love Lucy):
In conclusion: We should bring dancing back as a kickass pastime. Now please.
