A week after their marriage, the redneck newlyweds, Bubba and Arlene, paid a visit to their doctor.

"You ain't gonna believe this, Doc," said the husband. "My thingy's turnin' blue." "That's pretty unusual," said the doctor. "Let me examine you."
The doctor takes a look, and sure enough, the redneck's "thingy" really was blue.
The doctor turns to the wife, "Are you using the diaphragm that I prescribed for you?"
"Yep, shore am," she replied brightly.
"And what kind of jelly are you using with it?"
"Grape," she said.
