You know nothing about your books, George R. R. Martin.

GRRM recently stopped by “Late Night” to talk about his new book, “The World of Ice & Fire,” so Seth Meyers and Amy Poehler, both big fans of the author, took the opportunity to quiz him on how much he actually knows about his “Game of Thrones” characters.

Prepare yourselves. The truth is even more shocking than the Red Wedding.

“Late Night with Seth Meyers” airs weeknights at 12:35 a.m. ET on NBC.
