In a promotion for the teen star’s new movie role, That Awkward Moment, Zac Efron makes fun of his broken jaw. The actors justify the incident in the trailer.

“Zac was at home with a girl, giving her the worst sexual experience of her life. But she was getting into it, until she realized that you were finished.

“And this girl’s pent up sexual energy, that you failed to satisfy, made her angry. So angry that she picked up a book, a heavy book, and slammed it right into your beautiful face.”
