Duck walks into a bar and asks for a beer, the barman, astounded shouts out
"holy shit a talking duck!"
the duck, having heard this before sits down and explains his life story, how he was bred in a science lab, taught to speak and then when the lab was shut down he was cast out into the world on his own.
The Barman, clearly amazed says
"you should join the circus, it'd be just the job for you!"
the duck, confused replies
"why would the circus need a plasterer?"
