my fav gif is the Cain Valasquez one where he is doing the Mutumbo "no" finger after the match with Kongo.
Best part about it is if u look in the background Kongo is on his knees holding his face and bleeding from his nose, looking like bloody, beaten, broken mess. kinda funny cuz ppl say cain didnt "finish" kongo, that gif says otherwise IMO
Mark Hunt taking a CC LHK right to the melon is another great GIF. what a beast he just ate it like nothing
