Game of Thrones: 10 Most Inventive Deaths
9. Karl Tanner's Knife Through The Back Of The Head

Although the battle at Craster's Keep is pretty good, Tanner's death is certainly the stand out moment. Instead of chopping off his head or pushing his blade through Tanner's spine, Snow puts his sword through the back of Tanner's neck and out through his mouth, just as he's about to kill one of Craster's daughter-wives with his dagger.
There's just something perversely delightful about watching the surprise on his face as the blade smashes through his teeth.
