Redneck Sex

A week after their marriage, the redneck newlyweds, Bubba andSweet Pea, paid a visit to their doctor.
"You ain't gonna believe this, Doc," said Bubba. "My thingy's turnin' blue." 
"That's pretty unusual," said the doctor. "Let me examine you." 
The doctor takes a look. Sure enough, Bubba'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.
