Taking a roadtrip with your grandpa probably doesn’t sound like the most exciting way to spent a few days — unless your grandpa is Robert De Niro’s character in the upcoming Dirty Grandpa, a comedy about a grandson (Zac Efron) learning how to live on the wild side from his dear ol’ grandfather.

In the trailer, which first premiered on Buzzfeed, the two drive around Florida in a baby pink Mini Cooper while Grandpa Dick tries to lighten the mood, something that involves lots of nudity, plenty of alcohol, and even some (accidental) crack-smoking.

Watch the trailer below, and see the movie when it arrives in theaters Jan. 22.
