quackers

One Monday morning, at exactly 12 0, a duck walked into a bar, walked up to the bartender and asked 'do you have any quackers, mate?'. Everyone in the bar burst out laughing and the bartender replied, 'no sorry we don't have any of those!'. So the duck walked out of the bar. The next day, exactly 12 0 the duck walked in again and went up to the bar and asked 'do you have any quackers, mate?' and once again the whole bar burst into laughter, but did'nt find it quite as funny as yesterday. This continued everyday until Saturday. The duck would walk into the bar at exactly 12 0 everyday and would ask 'do you have any quackers, mate?' and everyday the whole bar would start laughing but each day finding it less and less funny. On Saturday the duck walked in and asked the barman the same question: 'do you have any quackers, mate?'. By this time the barman had got rather fed up with this duck and replied angrily 'no I don't have any quackers! And if you come in this bar one more time and ask for some quackers I'll nail your beak to this bar!!'. So the duck walked out and the next day everyone in the bar was waiting with baited breath for 12 0 to come. At last, 12 0 came and in walked the duck through the double swing doors. He walked up to the barman and asked, 'do you have any nails?' and the barman replied, 'no' looking puzzled, 'well do you have any quackers then?' asked the duck!
