Zac Efron appeared on The Ellen DeGeneres Show and got down with his bad self while promoting his new comedy film Dirty Grandpa.

The actor and the comedienne entertained the audience to a quick round of Heads Up, a show-favorite game that required Efron to pantomime phrases from the "bad behavior" deck while DeGeneres guessed.

In under one minute, Efron was challenged to act out "lap dance," "Tinder," "making out," "twerk," "skinny-dipping" and "handcuffs."
