The Mountain and the Viper (Season 4) from Best Game of Thrones Episodes
Pretty far down the list of Game of Thrones episodes that make us die from shock and reanimate next Sunday. Daenerys banishes Jorah Mormont and the Mountain clashes with Oberyn Martell. The latter injures the opponent and starts giving victorious speech, getting his head cracked by the giant in a few seconds. Ouch.
