School is back in session and The Lab proved that they are at the head of the class! Their performance on NBC's "World of Dance" was so phenomenal that even the judges lost their minds. Neyo, J-Lo, Derek Hough (from Dancing With The Stars) and principal ballerina Misty Copeland were in awe at the performance. I like great dancing, especially when a good beat is the backdrop. Props to The Lab, hope they take it all in the competition.
