A young boy is walking down the street with some chicken wire under his arm. His grandfather sees him and asks what he has. The child replies, "It's chicken wire and I'm going to catch some chickens." The grandfather chuckled, "Silly boy, you can't catch chickens with chicken wire." Later that night, the young boy walked down the street with 12 chickens behind him.
The next day, the grandfather saw him walking down the street with some duct tape under his arm. Once again he asks what the child is up to. The young boy says he is going to catch some ducks. The grandfather replies, "Silly boy, you can't catch ducks with duct tape." Sure enough later that night, he sees the boy walking down the street with 12 ducks behind him.
The next day, he sees the child walking with something else under his arm. He asks what it is. The boy replies, "Its pussy willow." To which his grandfather replies says, "Hold on, let me get my cane!"
