By Tom Galloway: Stephen Colbert’s opening on Wednesday night’s Late Show was devoted to mocking President Obama’s self-admitted inability to keep track of the names of all but one character in Game of Thrones, including Obama referring to Tyrion Lannister as “the dwarf.”

Or as Colbert phrased it, “President Obama’s…inability to keep track of conflicts between the bloodthirsty leaders in the unstable region of Westeros.”

Video of the whole episode here with the Obama stuff starting about 1:30 into the show.

The interview where Obama stated this was done by Bill Simmons back on October 5 due to Obama being GQ‘s Man of the Year.

What’s your guiltiest-pleasure TV show? Don’t say Game of Thrones, because that’s a good show. …

I do love Game of Thrones.

Which character do you identify with?

My favorite character is probably…the dwarf, what’s his name?

Oh, yeah. Peter Dinklage’s character.

The problem with Game of Thrones, though, is that I don’t remember the names of any of the characters.

I don’t, either.

I remember the characters, so when I watch it, I know exactly what’s going on. But if you read a review of the show afterwards and they’re mentioning such and such, the only one I remember is Jon Snow, because I can pronounce Jon Snow.
