The site How to Dance Properly [1] won't teach you how to moonwalk, but you can learn a variety of dance moves including:

• Stir The Pot, of Love
• Hanging Out . . . Casual
• Make Love to the Crowd
• Basic Twirl

Out of all of them, I think my favorite is "Elaine Ripped Me Off," inspired by Elaine's classic dance moves on Seinfeld.
