A farmer sits on his front porch and sees his nearly adult son walking out of the house wit a bundle under his arm.
Farmer asks, "Whatcha got there, son?"
The son, "Chicken wire."
Farmer, "Whatcha gonna do with it?"
Son, "Catch chickens."
Farmer, "Hold on, son, that's not how it works. You don't use chicken wire to catch chickens."
The son ignores his father and returns home a few hours later with a couple of chickens.
The next day, the farmer is sitting on his porch and sees his son leaving the house again.
Farmer "Whatcha got there, son?"
Son "Duck tape."
Farmer, "Whatcha gonna do with it?"
Son, "Catch ducks."
Farmer, "Hold on, son, that's not how it works. You don't use duck tape to catch ducks."
The son ignores his father and returns home a few hours later with a couple of ducks.
The next day, the farmer is sitting on his porch and sees his son leaving the house again yet again.
Farmer asks, "Whatcha got there, son?"
The son answers, "Pussy willow."
Farmer, "Hold on, son, let me get my hat!"
