Because you needed another reminder of why snakes are terrifying.
Remember when you learned in school that snakes can unhinge their jaws in order to eat very large food items? Oh, you blocked that out because snakes are disturbing abominations of everything we hold true about how animals should work? Right.
Well, behold, as this li'l guy opens his jaw to six times (or so) his height. It's half horror movie, half "I wish I could do that when I eat my feelings." I would find this video a lot less disturbing if the snake was eating an entire meat-lovers pizza and grocery-store sheet cake, though.
