One of the 'so shit it's good' ones. Duck walks in to a bar, asks the barman - "Got any bread?" Barman replies - "Nah, sorry." Duck leaves. Next day duck comes in again and asks - "Got any bread?" Barman - "No, no bread today either pal, sorry." Duck leaves. Duck comes in the next day - "Got any bread?" Barman - "Look, we don't have any bread, and we never will! OK?!" Duck leaves. Duck comes in the next day - "Got any bread?" Barman, in a fit of rage - "We don't have any bloody bread! If you ask again I'm gonig to nail your beak to the table, got it?!" Duck - "Got any nails." Barman - "no." Duck - "Got any bread?"
