There's no doubt that Bayern is a handsome horse, though I suppose he might not be completely thrilled with this moment that ended up being broadcasted on national television.
Then again, he might be really excited. Perhaps, he's thinking..."OMG OMG OMG I'M ON TV !!!!!!"
Or maybe he's really excited about his namesake, FC Bayern Munich, winning the German Cup today.
He's probably just excited about being on TV.
UPDATE: It appears he just wanted to say, "HAAAAAAAAAAAYYYY!!!!"
