A duck walks into a diner and orders coffee and a sandwich.
The waitress looks at him and says, "But you're a duck."
"I see your eyes are working," replies the duck.
"And you talk!" exclaims the waitress.
"I see your ears are working," says the duck, "Now can I have my beer and my sandwich, please?"
"Certainly," says the waitress, "sorry about that, it's just we don't get many ducks in this diner. What are you doing round this way?"
"I'm working on the building site across the road," explains the duck.
So the duck drinks his coffee, eats his sandwich, pays and leaves. This continues for 2 weeks. Then one day the circus comes to town. The ringleader of the circus comes into the diner and the waitress tells him about the incredible talking duck.
"Marvelous!" says the ringleader, "get him to come see me."
So the next day, the duck comes into the diner. The waitress says, "Hey, Mr Duck, I lined you up with a top job paying really good money!"
"Yeah?" says the duck, "Sounds great, where is it?"
"At the circus" says the waitress.
"The circus?" the duck enquires.
"That's right," replies the waitress.
"The circus? That place with the big tent? With all the animals? With the big canvas roof with the hole in the middle?" asks the duck.
"That's right!" says the waitress.
The duck looks confused and asks: "What the heck do they want with a plasterer?"
