A lady walked into a pharmacy and told the pharmacist that she needed some cyanide.
The pharmacist said, "Why in the world do you need cyanide?"
The lady then explained she needed it to poison her husband.
The pharmacists eyes got big and he said, "Lord, have mercy -- I cant give you cyanide to kill your husband Thats against the law Ill lose my license, theyll throw both of us in jail and all kinds of bad things will happen Absolutely not, you can NOT have any cyanide"
The lady reached into her purse and pulled out a picture of her husband in bed with the pharmacists wife.
The pharmacist looked at the picture and replied, "Well, now. You didnt tell me you had a prescription.
