A farmer approached his wife and told her that they needed to make some cut backs.
He touched her breasts and said "if we could get milk out of these, we could get rid of those cows."
Then he touched between her legs and said "if we could get eggs to pop out of here, we could get rid of those chickens."
She looked at him and grabbed his penis and said "if I could get this up, I would get rid of your brother."
