And, lo! The heavens parted, and within their divine light could be seen Zac Efron twerking and thrusting in Ellen DeGeneres’s face as part of a very special Dirty Grandpa–themed round of Heads Up! The chorus of women’s frenzied screams filled the studio as if they were being bodily taken up to Heaven for the Last Judgment. LOL, then Ellen played the lap dance again from her perspective. “If anyone ever tells you to twerk, just do it,” Zac Efron told the waiting crowd, and they knew it was right and good.
