A pretty blonde woman is driving down a country road when her car breaks down. She goes to the nearest farmhouse and knocks on the door. When the farmer answers, she says to him, ''My car broke down! I don't know what to do! Can I stay here for the night until I can get some help tomorrow?'' ''Well,'' drawls the farmer, ''you can stay here, but I don't want you messin' with my sons Jed and Luke.''

The blonde looks through the screen door and sees two men standing behind the farmer. ''Okay,'' she says. After going to bed, the woman begins to get a little hot thinking about the two boys in the room next to her. So she quietly goes into their room and says, ''Boys, how would you like for me to teach you the ways of the world?''

They say, ''Huh?''

She says, ''The only thing is, I don't want to get pregnant, so you have to wear these rubbers.'' She puts them on the boys, and the three of them go at it all night long.

Forty years later Jed and Luke are sitting on the front porch, rocking back and forth. Jed says, ''Luke? You remember that blonde woman that came by here forty years ago and showed us the ways of the world?''

''Yeah,'' says Luke, ''I remember.''

''Well, do you care if she gets pregnant?'' asks Jed.

''Nope,'' says Luke, ''I reckon not.''

''Me neither,'' says Jed. ''Let's take these things off.''
