A duck walks into this bar in Melbourne and says "Got any grapes?" and the bartender says "No we don't sell grapes!".
The next day the duck comes back and says "Got any grapes?" and the bartender says "No we don't sell grapes, and the next time you come in here for grapes I'm going to nail your feet to the ground!!"
So the next day the duck comes back and says "Got any nails?" and the bartender says "No, we don't sell nails" so the duck says "Got any hammers?" and the bartender says "No we don't sell hammers!" So the duck says "Got any grapes?"
