When Ahmed was just a youngster, he went to the drug store and asked the pharmacist,
"Sir, can you tell me where the ribbed condoms are?"
The pharmacist replied, "Son, do you know what condoms are used for?"
"Sure do replied Ahmed. They keep you from getting venereal diseases."
The Pharmacist was impressed. "That's right, son.
Do you know what the ribs are for?"
Ahmed paused, then answered, "Well, not really sir, but they sure do make the hair on my goat's back stand up."
