A lady walks into a drug store and tells the pharmacist she needs some cyanide.
The pharmacist said, "Why do you need cyanide?"
The lady said, "I need it to poison my husband."
The pharmacist’s eyes got big and he said, "I can’t give you cyanide to kill your husband! That’s against the law! I’ll lose my license. They’ll throw both of us in jail! 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 pharmacist’s wife.
The pharmacist looked at the picture and replied, "Well now, you didn’t tell me you had a prescription."
