Meet the grinning donkey that lives to please…

This is one donkey with great social skills.

Smiling on command, he charms the kids on a day out with gramps.

Sure, the wonder of a donkey that smiles to order wears off on these kids after a while, but for a minute there, he had them riveted.

"Grandpa! He's listening! Look at him!"
