A duck goes into a bar.
He waddles up to the bar and asks the barman "Got any bread?", to which the barman replies "Nope, we sell beer, not bread". "OK" says the duck, and he leaves.
Around the same time the next day, the duck returns and again asks the barman "Got any bread?". The barman again tells him that they sell grog, not bread. The duck leaves.
The next day the duck returns. "Got any bread?", he asks. The barman, now quite annoyed, replies with "Look mate, we sell beer. If you come in and ask for bread again, I'll nail your beak to the table!". The duck rolls his eyes and goes.
Sometime the next day, the duck wonders back in and approaches the bar. As the barman gives him an icy stare, he asks;
"Got any nails?"
"No, why?"
"... got any bread?"
