A duck walks in to a bar, he leans over the counter and asks the barman "got any fish?" the barman looks confused at first, as their is a duck talking then replies "no were a bar, we dont serve fish". Next day the same duck walks in to the bar, same question "got any fish?" barman annoyed "no i told you yesterday, we dont sell fish now get lost!" The duck comes back everyday for the next week asking the same question untill finally the barman cracks "no we dont have any fish and if you ask again im going to nail your beak to the floor!" next day duck walks in "got any nails?" barman cant beleive the ducks back "no we dont sell nails" duck looks at him and says " got any fish?"
