Contraception

A week after their marriage, the newlyweds paid a visit to their doctor.

"I can't figure it out, Doc. My testicles are turning blue," the husband said.

The doctor examined him and confirmed the unusual condition. He asked the wife, "Are you using the diaphragm I prescribed?"

"Yes," she replied.

"And what kind of jelly are you using?" the doctor asked.

"Grape." she said.
