A city fella was taking a ride in the country in his new convertible. After a while, he came across a farmer driving a tractor... and the farmer wasn't wearing any pants.

The man pulled up along side the farmer and asked, "Hey there, how come you're not wearing trousers?"

"Well, city boy," the farmer said, "the other day I went out working in the fields and I plum forgot t' wear me shirt. I Got back home that night and m' neck was stiffer than an oakwood board.

So, this here's my wife's idea."
