Do I really need to add a SPOILER ALERT? Better safe than sorry, I guess.
Last night's episode of Game of Thrones (S4:E8) featured one of the most grusome confrontations in television history. During Tyrion's trial by combat, The Red Viper of Dorne had The Mountain down for the count. But his vengeful hubris allowed The Mountain one final attack, and cost Prince Oberyn not only a victory, but also his head. As with most things related to Game of Thrones, it was heartbreaking and awesome all at the same time.
At any rate, it didn't take the Internet long to react to the horrifying scene. Here are our favorite GIFs and reactions from around the web.
