Conan O'Brien is no stranger to video games, sure he can hardly play UFC 2 or DOOM or Fallout 4… Ok, so he's not the best gamer, but he definitely tries. At least there's that and the fact that he's pretty entertaining.
As another part of his Clueless Gamer semgent, Conan O'Brien challenged the stars of Neighbors 2, Zac Efron and Seth Rogen, to a Mario Kart 8 showdown inside of a fraternity house. There was special rule for the frat-house Mario Kart challenge, the loser of each individual race had to have a penis drawn on them to tie-in to the college party themes in Neighbors 2.
Of course, Conan is on network television so his censors gave him a specific list of drawings that were ok and not ok for broadcast. Hilarity ensues throughout with many cleverly drawn male "private parts" being spread across the talk show hosts face. You can watch the full video above.
