My wife first saw this on Ellen and thought it was pretty funny, so I decided to pass it along. Some folks say that the donkey "sings" because the pitch of the violin hurts its big ears. I guess it's hard to say what makes an animal sing along with the folks who provoke them to do so. I try to get my cat "Hemmie" to sing, but a light squeak is about all I get. Anyway, enjoy this clip, straight from the farm, violin, donkey, and 4-year old close by watching it all.
