Was the biggest surprise of the evening on the 'So You Think You Can Dance' finale who won or was it watching Ellen DeGeneres recreate the season's hottest hip-hop number with tWitch?

We knew Ellen loves to dance, but who knew she could get down so hard -- nearly as hard as Alex Wong, who originated the amazing "Outta Your Mind" routine in week three?

"Who was the most inspirational dancer, this season?" mused producer Nigel Lythgoe after the finale. "I think it's Ellen DeGeneres. You laugh, but the public knows that she is not a dancer. This is somebody that has not had any lessons and there she is, absolutely brilliant. In her own words, I thought she was a carpenter because she nailed it tonight!"

The husband-and-wife choreography team behind the routine, Tabitha and Napoleon D'Umo (aka "Nappy Tabs"), told TV Squad how the Ellen hook-up happened.

"We worked with her last year (on her show) and she's such a fan of dance," Tabitha recalled. "She told us, 'I'm on my summer break and I'm a little bored, let's cook something up.'"

(S04E15)It's time to find out which dancers will be going on tour after So You Think You Can Dance ends this August. I'm going to put it out there now (I think it's time): I want either Joshua or Katee to win this competition. I think it would be especially nice if the girl they almost didn't put on the show won the whole sha-bang!

Other thoughts before we begin... Nigel is a little cranky lately. I don't like him chiding Cat. All she did was remind everyone to tune in to the finale. By the way, there's going to be a sick popping battle during SYTYCD's live finale. Awesome. My review of tonight's show is after the jump.
