Mr. and Mrs. Smith went to a sex therapist who promised to only take their case if he knew he could help them. After hours of tests, he agreed he could help. He told them to stop at the store on the way home and buy donuts and grapes. Mrs. Smith was to toss the donuts at Mr.Smith's erection and eat the ones that stayed on. Mr.Smith was to roll the grapes across the floor and eat the ones that became lodged in Mrs. Smith's love canal.

A few weeks later, the Jones came to see the doctor. "Our friends the Smiths told us to come to you." they said.

The doctor ran the tests and came back to the Jonses. He told them he was sorry but there was just nothing he could do. The Jonses said "You helped the Smiths, why won't you help us?"

After continued begging from the Jonses, the doc said "ok, ok... stop by the market on the way home and buy a box of Cheerios and a bag of oranges."
