We popped and locked and made the Soulja Boy dance craze look like the funky chicken. And it didn't matter if you had no clue what paso doble or fox trot meant, because MTV has brought the streets to the stage in the our brand new competitive dance series Randy Jackson Presents: America's Best Dance Crew! After scouring the country for the top street and studio dance crews, we found 12 of the very best groups to grace our stage. With their dreams on the line, these crews did their best to impress our panel of judges, including singers JC Chasez and Lil Mama and choreographer Shane Sparks, host Mario Lopez and, yes, American Idol's Randy Jackson. After the first dance-off, only the elite eight remained in the competition, and in the end, only one team was crowned America's Best Dance Crew.
