We can't we have nice things?
Because this is why. Nature hates us and John Lewis and Monty the Penguin and Madagascar and Benedict Cumberbatch's pronunciation of 'Peng-wing'. They and we are all ruined because seals have been caught having sex with penguins in the wild by the BBC and the journal Polar Biology and it's all very upsetting.
Apparently this isn't the first time a seal has been recorded engaging in sexual behaviour with a penguin, with scientists observing the behaviour on the sub-Anatarctic Marion Island and believe it could be a sign of sexual frustration or aggression by the seals towards the penguins that they share the environment with. Either way, it's ruined 99% of winter/Christmas programming for us. Watch with caution.
