King Arthur's Disasters S02E12 - Donkey Kong King

Princess Guinevere wishes to bathe in fresh donkey's milk, so once again Arthur finds himself in Spain transporting an ill-tempered donkey through the countryside. Here he meets the legendary Don Quixote, helps him battle a windmill, a lion and some rather disgusting tacos. But when King Arthur and Merlin proudly present the Princess with the donkey, she points out one small mistake - the donkey is male.
