Talking Duck

Duck walks into a bar and orders a beer. Barman says, "Hey, you're a duck"
"Nothing wrong with your eyesight," observes the duck.
"Yeah, but I mean - you can TALK" says the barman.
"Guess your ears are fine, too," answers the duck. "Now, can I have a beer please."
Barman serves the duck a pint and asks him what he's doing in the area.
"Oh," says the duck. "I work on the building site over the road. We'll be here for a couple of weeks, and I'll be in each lunchtime for a pint."
And each day the duck waddles over from his job at the building site and has his lunchtime lager.

Next week, the circus comes to town on its annual round. Circus owner comes in for a pint, and the barman tells him about the talking duck. "You should get it into your circus," he says. "Make a lot of money out of a talking duck. I'll speak to him about it."

Following day, the duck comes in at lunchtime. Barman says: "You know, the circus is in town, and yesterday I was chatting to the owner. He's very interested in you."
"Really?" says the duck.
"Yeah. You could make a ot of money there. I can fix it up for you easily."
"Hang on," said the duck. "You did say a CIRCUS, didn't you?"
"That's right."
"Big canvas tent?"
The duck looks puzzled. "What the hell would he want with a plasterer?"
