First of all there are ducks in Star Wars.

A friend of mine told me this true story:

A man had to go to work and left his daughter at his sisters to be baby-sat for the day. She found a stuffed duck to play with all day that was wearing a blue bandana. After they got home that evening his daughter started telling him all the animals she liked. Then a little game started when she asked: "What does the cow say?" Her Dad replied, "Moo!" This went on through several animals until she asked: "What does the Duck say?" Her Dad replied, "Quack! Quack!" Then she said: "No silly, he says Aflac! Aflac! AFLAC!"
