The fourth season of "So You Think You Can Dance" kicked off Thursday night with a two-hour audition show from Los Angeles. Host Cat Deeley and regular judges Mary Murphy and Nigel Lythgoe were joined by Mia Michaels as they came face to face with the best and, of course, the worst that the dancing world had to offer.Dancers got one minute in front of the judges, and those with overwhelming "yes" votes moved on to the next round in Las Vegas, absolute "no" votes went home, and in-between dancers would be brought back at the end for a second chance in a group choreography routine.The first real joker of the evening was the man they call "Sex," who was making his third audition show appearance and, once again, making a fool of himself. Nigel lambasted the guy, telling him he "must just enjoy watching himself look stupid on television." And Nigel refused to call him "Sex" anymore, either.A visually impaired girl named Laura tried her best, but the judges didnt think her choreography was strong enough to remain in the competition. Mia, though, got very emotional and called the girl an inspiration because she had a close friend who lost their eyesight.
