Five minutes later the duck returns and asks the bartender if he has any olives. “I told you before, we have cherries, but WE DON’T HAVE OLIVES!” says the barman. “Oh,” says the duck and leaves.
Five minutes later, the duck comes back the third time and again asks, “Have you got any olives?” “Look,” screams the barman, “For the last time WE HAVE NO OLIVES! We will never have ANY OLIVES and if you ask me once more, I am going to nail your webbed feet to the floor!!!” “Oh,” said the duck and left.
Five minutes later the duck walks through the door and the bartender immediately goes off on him. The duck stops him and said he was just wondering if he had any nails. "Nails!" Why would I have nails...this is a bar!"
“Okay,” said the duck, “So, have you got any olives!?”
