An old farmer is sitting on his front porch watching the sunrise when he sees the neighbor's kid walk by carrying a spool of something metallic under his arm. "Hey boy, whatcha got there?"
"Chicken wire."
"What you gonna do with that?"
"Gonna catch some chickens."
"You damn fool! You can't catch chickens with chicken wire!" says the old man.
The boy just laughs and keeps walking. That evening at sunset, the boy walks by, dragging behind him 30 chickens caught in the chicken wire.

The next morning, the old man sees the boy walk by carrying a shiny roll of something. "Hey boy, whatcha got there?"
"Duct tape."
"What you gonna do with that?"
"Gonna catch me some ducks."
"You damn fool! You can't catch ducks with duct tape!"
The boy just laughs and keeps walking. That evening at sunset, the boy walks by, trailing behind him 30 ducks caught in a long trail of duct tape.

The next morning, the old man sees the boy walking by carrying a branch behind him. "Hey boy, whatcha got there?"
"It's a pussy willow."
"Wait up," says the old man. "I'll get my hat!"
