"Life here is good," says the narrator, "but this husband has come home to find his wife with another penguin. He flips out. His strategy is simple: batter the homewrecker."
We then see the husband penguin begin to hit his romantic rival with his flippers, which may as well be "baseball bats," the narrator says.
After things end in a stalemate, the female joins the fray to choose her man - the homewrecker.
But the daddy penguin is not to be denied. He follows them to their burrow where goes at the other penguin with his beak.
After a bloody second round, the female penguin again chooses her lover.
"He makes one last plea to the female, but she's got no time for losers," the narrator says coldly as the husband uses his less than happy feet to walk away from his lost love.
Social media, of course, went meme-crazy with this one, but who could blame them?
