Game of Thrones stars Peter Dinklage & Lena Headey play Conan in a video game

(TBS)

Can six seasons of Game of Thrones prepare you for video games? On-screen brother-sister duo Peter Dinklage (Tyrion Lannister) and Lena Headey (Cersei Lannister) found out Monday when they stopped by Conan for a round of Overwatch, out Tuesday.

The action began long before the game, with O’Brien ripping apart a faux Iron Throne as Dinklage and Headey sat on folding chairs unlike anything you’ve seen in King’s Landing. “No expense was spared,” O’Brien joked. “These are made of Starbursts. Then they put some shoe polish on it.”

Headey changed the topic to automatic toilets — about which Dinklage and O’Brien had much to say. Soon, O’Brien summoned someone to explain the rules and the game eventually began. Among the highlights: Headey taking on enemies with multiple guns, and Dinklage and O’Brien discussing the rather perky butts in the game.

Watch it all unfold in the video below.
