Ruth said "That sounds easy enough. I can do that."
The doctor ran into Ruth a couple of weeks later and asked whether their plan had worked. She replied, "Doctor, I am so mad about that I can't see straight!"
He looked at her and said, "What happened, did you grind it up like I told you?"
She responded, "I ground it up, put it in his morning coffee and pretty soon it must have taken effect. He grabbed me, threw me on the table and rips off my clothes. He then rips off his own clothes and in a moment we're acting like a couple of newlyweds."
The doctor then stated, "Well what's the problem? I thought that was what you wanted."
She said, "You don't understand, Doc. They've banned us from McDonald's for life!"
