A woman walks into a drug store and tells the pharmacist that she needs some cyanide.
The pharmacist says, "Why in the world do you need cyanide?"
The lady then explains she needs it to poison her husband.
The pharmacist's eyes got big and he said, "Lord have mercy - I can't give you cyanide to kill your husband! That's against the Law! I'll lose my license! They'll throw us both in jail and all kinds of bad things will happen! Absolutely not! You CANNOT have any cyanide!"
The woman reached into her purse and pulled out a picture of her husband in bed with the pharmacist's wife.
The pharmacist looks at the picture and says, "Well now; you didn't TELL me you had a prescription!"
