...this is it as best as I can remember it; it was in the memory book from Grandpa's funeral:
Grandpa said he had a hunting dog that could bring home a raccoon all by himself. There was a good market for 'coon pelts at the time, so this was a valuable dog to have around. Grandpa had the habit of setting the boards for stretching the pelts, just outside the back door, before setting out on the hunt. He had different sized boards for different sized pelts. Some days, Grandpa would have a request from a local dealer for a larger pelt, so he would set out the bigger board. Other days the buyers weren't so particular, so he would set out the smaller board.
The dog was clever enough that he started going after coons as soon as he saw the boards set out; and he would bring home a bigger one first if he saw the bigger board set out.
This system worked really well for several months, and finally Grandpa was only going hunting when he felt like taking a long walk; the dog was bringing in as many pelts as he could sell, without his help, and all the right size.
Then Grandpa met Grandma, and married her, and brought her home. The first Monday after their wedding, she set up to do the washing, and because it was a bright, sunny day, set the ironing board outside the back door.
Grandpa said that was the last he ever saw of that dog....
