Oh, I bet Veeblefester wishes you all were donkeys. Donkeys actually do things like being pack animals for people in underdeveloped countries. They also can serve as kind of a service animals for horses to deal with stress and anxiety. Some donkeys are also kept for their milk and meat.
I would say the employees at Veeblefester Tea Cozies, Inc., or at least Brutus, are more like, what's a worthless farm animal? Legless chicken? Sheep with alopecia? Hei-Hei?
