Dog, feeling a bit funny, strains and poops, he steps away and reveals his own poop, feeling relieved. Dog looks up and steps away quickly as poo is about to fall on him. Suddenly, birds poo into his mouth, dog turns green and barfs. Some of it gets on owner's shoes. Owner gets mad, hits dog with paper, and takes dog away.
Paper hits birds and birds fall into dog's poop.
Dog sees this and continues walking, happily wagging its tail.
