The Duck --------

One day, the duck walked into a chemist and asked, "Got any duck food?". The chemist replied, "Sorry mate, we don't sell food here." The duck turned around and walked out.

The next day, the duck returned to the chemist and asked, "Got any duck food?". The chemist replied, "Look, I told you! This is a chemist and we don't sell food here! Try a pet store or something!" The duck turned around and walked out.

The next day, the duck returned once again and asked, "Got any duck food?". The chemist, really pissed off at this point in time yelled, "LOOK! WE DON'T SELL DUCK FOOD HERE! SO GET OUT!! AND IF YOU RETURN HERE AGAIN, I'M GUNNA GET SOME NAILS AND A HAMMER AND NAIL YOUR BLOODY WEBBED FEET TO THE FLOOR! NOW PISS OFF!" The duck turned around and walked out.

The next day, the duck returned. He walked into the chemist and asked, "Got any nails?". The chemist, really pissed off yelled, "NO!!!!!!!" The duck said, "Good. Got any duck food?"

I said "duck", you know.
