In the Big Bounce, before the Dance Off begins between The Lil Saints and the crew in black, Lil' Kim says that the music will play for five minutes and when she says "stop" they must stop dancing. But she never actually says stop, the music just fades out and the dancers stop dancing.
During the Big Bounce, right after Lil' Kim announces both Wade's Crew and the Lil Saints have tied, Wade strides up next to her. But when it cuts to the next shot, he's seen from the back standing with his crew. When it cuts back to Lil Kim, Wade is not standing by her (this whole sequence takes about 2 or 3 seconds).
