A farmer walked into a drug store and said to the pharmacist, "I want me one of them thar condoms with pesticides on it. Where do I find 'em?"
The pharmacist replied, "Oh sir, you must mean that you want the condoms with SPERMICIDE, not pesticide. They're on aisle 4."
"No, no, I want me them thar condoms with PESTICIDE on it," growled the farmer.
"Sir," said the pharmacist, exasperated from explaining, "PESTICIDE is for killing insects, SPERMICIDE is for killing sperm. I'm sure that you mean spermicide instead of pesticide."
"Listen here," argued the farmer, "my wife's got a bug up her ass and I'm a goin' huntin' for it. Like I said, I want me one of them condoms with PESTICIDE on it!"
