The problem was their nooner: it took Homer a half hour to travel home and another half hour to return to the fields and he just wasn't getting enough work done. Finally Homer asked the town doctor what to do.
"Homer," said the doctor, "just take your rifle out to the field with you and when you're in the mood, fire off a shot into the air.
That will be Darlene's signal to come out to you. Then you won't lose any field time."
They tried Doc's advice and it worked well for a while until one day, when Homer came back to the doctor's office.
"What's wrong?" asked the Doc. "Didn't my idea work?"
"Oh, it worked real good," said Homer.
"Whenever I was in the mood, I fired off a shot like you said and Darlene'd come runnin'.
We'd find a secluded place, make love, and then she'd go back home agin."
"Good, Homer. So what's the problem?" asked the Doc.
"Ah mighta trained her too good. I ain't seen her since huntin'season started."
