Prinny again

On my Blip yesterday I speculated that horses must be able to sleep standing up, as Prinny was often seen apparently dozing in this spot. I'm sure everyone was convinced I was right but there may have been a few people out there who had a bit of doubt about it. So I say to those doubters, I present you here with indisputable proof that horses do indeed go to sleep standing up.
