Jessica Richens and Twitch Boss danced Hip Hop on So You Think You Can Dance 11 Wednesday, August 6, 2014.

Nappy Tabs was the choreographer.

Music was "U Got Me Up" by Cajmere.

This was a new dance called the Bobble Waffle.

"Unreal," said guest judge Tara Lipinski. "I'm obsessed with Twitch."

"It was out of this world," said judge Mary Murphy. "It was so good to have them back (Tabitha and Napoleon)."

"So pleased that I have inspired Napoleon and Tabitha to do this routine," said head judge Nigel Lythgoe. "Twitch really suits being an old man."
