Embarrassing Consequences of Losing to Zac Efron and Seth Rogen in Mario Kart

On Thursday’s Conan, Seth Rogen and Zac Efron battled Conan O'Brien in a frat house style game of Mario Kart. Though it was supposed to be a friendly game, Efron and Rogen wanted to raise the stakes. If a person lost the race, the others would draw male genitalia on them.

Before they began playing, O'Brien brought out a keg of green-tea kombucha and some sort of healthy vape pen, the nerdier version of the frat staple.

O'Brien won the first race and Rogen lost — but before they could drawing on him, O'Brien provided instruction on just how graphic they could get in sketching genitalia while still appeasing TBS standards and practices.

In the end, O'Brien’s luck ran out and his face was covered in crude drawings. It looked like he passed out at a keg party that was sponsored by a marker manufacturer.

Conan airs weeknights at 11 p.m. on TBS.
