This post contains spoilers from Game of Thrones Seasons 1-4. Read at your own discretion.
Game of Thrones Season 4 comes to a close on Sunday, leaving you as cold and lonely as Jon Snow north of the Wall. But before you must leave the Night's Watch, it's time to get your brain as sharp as a Valyrian sword.
From hidden Easter eggs (ahem, dragon eggs) within the hit HBO series to changes in characters from George R.R. Martin's novels, these facts will make you more clever than Littlefinger is creepy (and that's a lot).
Unfortunately, these trivia tidbits won't save you from death by dragon fire. Or eye-gouging. Or poison. Man, there's a lot of killing in this show.

1. Author George R.R. Martin has been writing A Song of Ice and Fire since 1991 on a MS Dos Word Processor.
No wonder it's taking so long to finish those books.
2. Game of Thrones actors have interesting ancestry.
Oona Chaplin (Talisa Stark) is Charlie Chaplin's granddaughter, Kit Harrington (Jon Snow) is a descendent of Charles II of England and Harry Lloyd (Viserys Targaryen) is Charles Dickens' great-great-great grandson.
3. HBO has made several changes to characters from its depictions in Martin's books.
Daario Naharis is supposed to have blue hair and Jorah Mormont isn't the most attractive of fellows.
4. Actress Emilia Clarke (Daenerys Targaryen) wasn't faking her disgust when she had to eat a horse heart in the first season of the show.
It was supposed to taste like gummy bears, but didn't.
5. There's a hidden Monty Python reference in Season 4.
Your mother was a hamster and your father smelled of elderberries!
