These are a couple videos of two sea lions (or is the second one a seal? Or are they both people in animal costumes?) screaming like angry men. "Why?" Why do they yell like that or why did I post it? Because I think you and I know the answer to both those questions is I have no clue.
Keep going for the videos.
Thanks to hairless, who agrees sometimes you just need to yell like a dad losing his mind.
