Any Grapes?

A duck walks into a convenient store and asks, " Do you sell any grapes here?"

The manager says, " No, we don't sell grapes."

The next day the duck waddles into the store and asks, "Do you sell grapes here?" The manager says, " No, we don't."

The third day the duck meanders into the store and asks, "Do you sell grapes here?"

The manager says, " Look! If I told you once, I told you three times, we dont see grapes here!

The next time you come in here asking for grapes, I am going to nail your webbed feet to the wall!"

The following day the duck enters the store and asks, " Do you have any nails?"

The manager says, " No. We don't sell nails here."

The duck says, " GOOD. Do you have any grapes?"
