Hounds       
He was a general practitioner in a small town in Iowa.
He liked being a doctor, but he liked coon hunting even more.
He liked coon hunting so much that he had 40 coonhounds.
That many dogs took a lot of food.
The doctor found a way to keep his dog food bill down by scrounging food from the local school.
There was a great deal of the school's hot lunch program that went uneaten right into a garbage can.
The dogs loved the stuff.
The dogs loved the recycled hot lunch program food so much that when summer vacation arrived, the hounds would stage a bit of a hunger strike before they'd eat the summer replacement fare.
