After a slamming hip hop routine to open the show -- it ended with Gev holding a headstand for what seemed like five minutes, and host Cat Deeley couldn't even throw him off by tickling his ribs -- it was time to eliminate two more dancers on "So You Think You Can Dance?" As usual, the bottom three couples would be asked to perform individual routines in their own styles, with the judges making the final decision on which guy and which girl would go home. Guest judge Mia Michaels again joined regulars Mary Murphy and Nigel Lythgoe.
