Talking people is one thing (with the brain function and vocal physicality to make it happen). A donkey is quite another. You can just image them writing it:
"Well, I think you pulled it off with the talking baby, mate, can you just push it that bit further?"
"What with?"
"Ohhhh, I dunno.....how about a donkey"
Come to think of it, we were sent to Sunday school so that our parents could engage in amorous dalliance after Sunday lunch. Who then were the donkeys?
