'Game of Thrones': Watch the Cast Crack Up in a New Blooper Reel [Video]

Considering how grim things are in Westeros, it's nice to see that the Game of Thrones cast is able to share a laugh every now and then amidst all the beheadings, stabbings, and eye-gougings. A newly released blooper reel from GoT's fourth season reveals some of the blown lines and literal slip-ups — better hold onto the bannister next time, Littlefinger! — that occur in the making of the HBO mega-hit.

Other bits of funny business: a moment where Tywin learns that the Iron Throne perhaps isn't as steely as it appears, Tyrion promising that the bit of dialogue he's forgotten is "a funny line," and a kiss between Joffrey and Margaery that literally knocks the boy king's crown loose. (Such is the apparent power of Natalie Dormer's lips.)

Enjoy the laughs while they last, folks. When Season 5 begins, things are likely going to get real bloody, real fast.

Game of Thrones premieres April 12 at 9 p.m. on HBO.
