A redneck goes to his family doctor for a physical. The Dr. begins by examining his feet and finds a peculiar deformity in the man's toes..."What happened here?" he asks..."That's Tolio!" the redneck says.."Tolio? You mean Polio!" the Dr. says..."no, no...it's Tolio....what kind of a Dr. are you?...never heard of Tolio!?!"
The Dr. then moves on to the fellows knees and again finds a peculiarity..."What happened here?" the Dr. asks...."That's Kneesels!" the redneck says...."Kneesels? You mean Measels!" the Dr. says...."no, no! It's Kneesels.....you never heard of Kneesels either?!? Just what kinda Doc are ya?!?"
The Dr. then asks the redneck to remove his pants and underwear and then resumes the examination. Immediately he blurts out "What's this then?.....Small Cox!?!"
