Ma and Pa farmer were sitting out on the stoop. Pa farmer reached over to Ma, grabbed her boob and said, "You know, Ma, if I could get milk out of them things, I surely wouldn't need all those cows over there."

Pa then grabbed Ma's crotch and said, "You know, Ma, if I could get eggs out of this thing, I wouldn't need all those chickens over there."

Ma looked at Pa, grabbed his pecker and said, "You know, Pa, if I could get a hard-on out of this thing, I wouldn't need the neighbour."
