A couple, the Browns, decide to find a therapist to spice up their love life. They finally decide on one that advertises he won't take your money unless he can help. They go to the appointment and have lengthy physical and psychological exams.
They meet the therapist and he says, "I believe I can help you". The Browns are ecstatic and listen intently.
He says to them, "Tonight, on your way home, I want you to stop at the grocery and buy grapes and donuts. When you get home I want you to both undress in the living room. Sir, I want you to roll the grapes on the floor with your nose, all the way across the room and into your wife's crotch. Then madam, I want you to take the donuts and see how many ringers you can score on your husband".
They call back in a few days to say their new games have really spiced things up. The Brown's are so happy, they tell their friends, the Smiths about it.
So they go to see the therapist. The therapist meets with them and says, "I'm sorry I cannot take your money as I cannot help you". They beg and beg, and finally the therapist gives in...
"On your way home tonight I want you to stop at the grocery and by apples and cheerios".
