SNL sia

WIGGING OUT: Is the costume of Maddie Ziegler, the tween dancer from Sia's "Chandelier" video, going to dominate this Halloween? If this sketch from the last SNL is any indication, trick-or-treaters will be twirling; host Jim Carrey and cast member Kate McKinnon both show up at an office party in the trademark blonde wig and flesh-colored leotard. Who'll win the costume contest? Only a dance-off will settle things. (10/27a)
