A week after their marriage, the Redneck newlyweds paid a visit to their doctor...
"I can't figure it out doc, and I'm really worried," said the husband.
"My testicles are turning blue."

"That's pretty unusual," said the doctor. "Let me examine you."

The doctor takes a look. Sure enough, the Redneck's testicles are blue.
The doctor turns to the wife. "Are you using the diaphragm that I prescribed?"

"Yes, I am," she replied.

"And what kind of jelly are you using with it?"

"Grape"
