A little Okie boy goes to the drugstore for some condoms. He goes up to the pharmacist and asked him,"Sir, can you tell me where the ribbed, lubricated condoms are?"
The pharmacist replied, "Son, do you know what condoms are used for?"
"Sure do" replied the boy, "They keep you from getting venereal diseases."
"Yes, that's true," said the pharmacist, "do you know what the lubrication is for?"
"Yessir, for ease of entry" replied the li'l Okie.
"Yes, yes" said the pharmacist, "but how about the ribs? What are they for?"
The little Okie boy thought for a moment, then looked up at the pharmacist and replied, "Well, they don't do a whole lot for me, but they sure do make the hair on the backs of them goats stand straight up."
