A man walks into a drug store and asks to purchase some cyanide. The druggist replies it is a controlled substance and is not for sale. The man pleads but his request is turned down each time.

"You don't understand" the man says, "I need the cyanide to kill my wife." The druggist is even more taken back and states he won't be apart to such a crime.

"But my wife is the meanest and nastiest woman on planet" the man continues. "NO" is the final reply of the druggist.

The man pulls out a picture of his wife from his wallet and shows the druggist who proceeds to study the photo of a few seconds.

"It will be just a few minutes to prepare the cyanide" the druggist says. "I didn't realize you had a prescription."
