A married couple, the Greens, were having problems in their love life. They went to a therapist who told them that he would perform a free examination. If he was able to help the couple, he would.
The therapist performs hours of examinations and questions. Finally he says,
"Ok, Mr. and Ms. Green. I can help. When you leave here, go to the grocery store and buy a box of donuts and a bunch of grapes. When you get home, take off all of your clothes and sit on opposite sides of the room from each other."
He looks at Ms. Green, "You will take the donuts and try to toss them across the room until you land one on your husband's love muscle, like a carnival game. After that, crawl across the room on your hands and knees and eat the donut without using your hands."
He turns to Mr. Green, "You will take the grapes and try to toss them into your wife's hoohah. Once you get one in there, crawl across the room on your hands and knees and eat the grape without using your hands."
The Greens followed the therapist's instructions and it worked perfectly. Their love life was better than when they first started dating. They were so happy that they told their friends, the Browns, about the therapist.
The Browns were also having problems in their love life, so they went to the therapist. The therapist performed his examination and asked his questions. When he was finished, he told the Browns that he couldn't help them.
The Browns begged and pleaded. They offered to double, then triple his fee. They were desperate!
"Fine!" The therapist says, "After this, I need you to go to the grocery store. You're going to need to buy a bag of oranges and a box of Cheerios..."
