The opening dance was a cool, futuristic hip-hop looking deal that was pretty captivating. Guest judge Toni Basil's speech about how she got into dancing, not so much. Host Cat Deeley asked Basil to talk about how much of a challenge it is for the dancers to learn all the different styles they have to know on the show and Basil's response was, essentially, that there are all kinds of dance and you'll never be able to master them.
