Edgar is sitting in his rocking chair on his back porch...

... watching the river flow, when he notices an old man down by the dock loading up his boat with rolls of tape.
Edgar yells down to the old man,
"Hey old man! Where you going with all that tape?"
The old man replies,
"This here is duck tape. I'm gonna catch me some ducks. You want to come with me?"
Edgar busts out laughing,
"Crazy old man! You can't catch ducks with duck tape!"
The man putts off down the river.
Later on in the evening, as the sun is getting low, Edgar sees the old man come putting around the bend. His boat full of ducks.
"I'll be damned."
The next day Edgar is stilling on his back porch rocking away when he notices the same old man down by the dock. This time he is loading up his boat with packets of sugar.
"Say there old man! Where you going with all that sugar?"
The old man looks up and says,
"This here is NutraSweet. I'm gonna catch me some nutrias. You want to come with me?"
Edgar busts out laughing,
"Crazy old man! You can't catch nutrias with NutraSweet!"
The man putts off down the river.
Later on in the evening, as the sun is getting low, Edgar sees the old man come putting around the bend. His boat full of nutrias.
The next day, rocking away on his back porch, Edgar notices the old man down by the dock. This time the old man is filling his boat with sticks.
"Hey old man! Where you going with all those sticks?"
"This here is pussy willow..."
"Hold on! Let me grab my hat!"
