Late night talk show host and comedian Conan O’Brien has brought Nintendo’s Mario Kart 8 onto tonight’s Clueless Gamer Segment. He was joined by actors Seth Rogan and Zac Efron, who raised the stakes on the races with some classic frat house-style antics. Without spoiling too much, the video hilariously appears to skirt the line on acceptable safe-for-broadcast standards. You can watch it for yourself in the embed below.

Like many of the other games O’Brien has played in the segment, Mario Kart 8 proved to be a quite challenge for the host. The game was released exclusively for the Wii U in 2014 to positive reception, earning 8 out of 10 in GameSpot’s review. We praised the game for its excellent racing mechanics, assortment of interesting tracks, and level of challenge, but criticised the weak selection of characters.

You can see which other games O’Brien has struggled through in other Clueless Gamer segments including Doom, Far Cry Primal, Fallout 4, The Witcher 3: Wild Hunt, and Call of Duty: Advanced Warfare.
