US President Barack Obama attempted to name all the characters of the hit TV show “Game of Thrones” who have died over the span of its six seasons.

In a new video titled “5 Things That Are Harder Than Registering to Vote”, the US leader attempted to name all of the dead characters with mediocre success, reports

“All right, you got Ned, Rob, Khal Drogo, Jon — but maybe that doesn’t really count. Renly, Summer, Shaggydog and then Hodor, that was sad,” he said.

With over 100 characters dying in the series, Obama said “that stuff’s hard”.

Obama is also seen trying his hand at other “difficult” tasks including untangling headphones, which he gave up on, playing “operation”, making a friendship bracelet and stacking Cheerios.

The video was done in part to coerce Americans to register to vote for this year’s upcoming election.

Last year, for a similar video, the US president doodled pictures of Michelle Obama, made funny faces in the mirror and played with a selfie stick to get citizens to sign up for health insurance.
