A duck walks into a bar and says to the bartender 'got any bread'
Bartender replies 'no... We sell drinks?'
The duck leaves and returns the next day.
'Got any bread?' asks the duck
The bartender becomes annoyed 'no! We are a pub and only sell drinks! And if you come here and ask again for bread I'm going to nail your beak to the feckin bar!!!'
The duck quickly leaves only to return the next day and shyly asks the bartender 'got any nails?'
The puzzled bartender replies 'no'
And then the duck blurts out 'got any bread!!!'
