Game On! Watch Seth Rogen, Zac Efron & Conan Face Off In Nintendo

It's a battle of the bros! Neighbors 2: Sorority Rising stars Zac Efron and Seth Rogen joined Conan O’Brien in a heated game of Mario Kart on Nintendo during a new installment of Clueless Gamers.

The game took place in the house where both Neighbors films were made, which is portrayed as a frat house in the movie.

Efron, 28, and Rogen, 34, made the rules even more interesting with a typical frat move: Whoever loses the game has to get a drawing on their face!

O’Brien, 53, tried his best to bro out with them. He brought his kombucha tea keg and his vape, but Efron and Rogen didn’t seem that impressed.

The show host lived up to the name of his series, as he lost almost every round. Efron and Rogen then had their fun drawing “network approved” drawings on his head.
