A lady walks into a drug store and tells the
pharmacist she needs 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 pharmacist's eyes got big and he said,
"Lord have mercy, I can't give you cyanide to kill
your husband! I'll lose my license, they'll throw both
of us in jail! Absolutely not!"

Then 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."
