Donkey, think of the saddest thing that's ever happened to you!

Oh, man, where do I begin? Well, first there was the time that old farmer tried to sell me for some magic beans, I ain't never got over that. Then this fool went off and had a party, and he had all the guests try to pin the tail on me! Then they all got drunk, and started beating me with a stick going, "Piñata, piñata!" What is a piñata anyway?!
