Cletus is passing by Billy Joe's hay barn one day when, through a gap in the door, he sees Billy Joe doing a slow and sensual striptease in front of an old John Deere tractor.
Buttocks clenched, he performs a slow pirouette, and gently slides off first the right strap of his overalls, followed by the left. He then hunches his shoulders forward and in a classic striptease move, lets his overalls fall down to his hips, revealing a torn and frayed plaid shirt.

Then, grabbing both sides of his shirt, he rips it apart to reveal his stained T-shirt underneath. With a final flourish, he tears the T-shirt from his body, and hurls his baseball cap onto a pile of hay.
Having seen enough, Cletus rushes in and says, "What the world're ya doing, Billy Joe ?"
"Good grief, Cletus, ya scared the bejeebers out of me," says an obviously embarrassed Billy Joe ...
"But me 'n the wife been havin trouble lately in the bedroom d'partment, and the therapist suggested I do something sexy to  a tractor."

(Don't make me come splain this to you! Just read the last line again, slowly.)
