Watch Seth Rogen, Zac Efron Draw Penises on Conan O’Brien’s Face (Video)

“Neighbors 2” stars punish TBS late-night host for losing a game of “Mario Kart” in latest “Clueless Gamer” segment

Talk about a dick move.

Conan O’Brien got a new look last night — and it’s just about a dozen penises drawn on his face.

The TBS late-night host joined Seth Rogen and Zac Efron at their “Neighbors 2” frat house to throw down in the latest “Clueless Gamer” installment. The fellas played “Mario Kart 8,” and to the loser, went the phallus drawings. The winners had the honors.

But they also had guidelines, provided by Turner. Not only was there a half-graphic chart to follow, there was an email, which read: “The outline of a penis can be shown, but should not be overly graphic or detailed. We cannot show depictions of the penis urinating or ejaculating.”

Conan actually won the first race, quite unexpected for the terrible video game player. Loser Rogen took his penis drawing on the forearm, probably because of filming. The next 10-plus losses all went to the “Conan” host, and his face was soon covered in male genitalia.

“You know what’s nice? I’m going straight from this to lunch with my in-laws,” O’Brien quipped.
