I was surfing channels late Saturday night and watched a few minutes of "So you think you can dance". This group of women had just finished dancing, but I really wanted to see it.

They had on robot-like outfits, and in their dance they did robotic moves and mirroring. Can anybody tell me who they were?
I tried...that's why I'm here! I don't have their name, the date they aired, or anything. This was the first time I'd ever seen the show, and it was in the middle of the night. I googled using every keyword I could think of and got nothing. I came here hoping that someone else had seen them.
Besides, if everyone just "googled it"...Yahoo Questions and Answers would have no purpose, lol.
