A little boy is walking holding chicken wire...

He walks passed an old man on a porch.
"Whatcha got chicken wire for?"

"Gonna go catch some chickens!" Says the little boy.

"You can't catch chickens with chicken wire you damn fool!"
The boy just walks off laughing. Around sunset the boy is walking back up and sure enough, he's dragging ten chickens behind him.

The next morning the boy walks down the same path and sees the old man.
"Whatcha got duck tape for?"
The boy responds,

"I'm gonna go catch some ducks!"

"You damn fool! You can't catch ducks with duck tape!"

The boy just laughs and carries on.

Come sundown, the boy heads back passed the old man with 20 ducks strung along the duck tape behind him.

The next morning the boy is walking down the field again, and the old man can't see what he has.
"Whatcha got there?"

"Pussy willow."

"Hang on, I'll grab my hat"
