Ok, so a duck walks into a bar and asks "got any crackers?" The bartender says no and the duck walks out. The duck walks in the next day and asks, "got any crackers?" The bartender says no. The duck walks out. The duck walks in the next day and asks, "got any crackers?" The bartender says, "I told you yesterday and the day before that no! and if you ask that one more time I'll nail your beak shut!" The duck walks out. The duck comes back the next day and asks, "got any nails?" The bartender says no. The duck says "good. Got any crackers?" Ba-dum-dum.
