Watch Kit Harington Explain The Game Of Tennis Very Thoroughly

Just like Jon Snow, Kit Harington knows nothing, at least when it comes to his tennis player, Charles Poole.

In a new clip from HBO's upcoming sports mockumentary, "7 Days In Hell," Harington's Poole proves to be quite the dimwit. When an interviewer asks Poole how he continues to be the No. 2 tennis player in the world, Poole responds with a thorough, step-by-step explanation of how to play tennis. Oh, sweet, blockheaded, beardless Harington.

"7 Days In Hell" follows Harington's Poole and Andy Samberg's Aaron Williams during a (fictional) epic weeklong Wimbledon match. Watch the two tennis rivals duke it out on the court when the mockumentary airs on HBO on July 11.
