(Trying to remember how it was told....)
A woman goes into her local pharmacy one day and says to the pharmacist..."I need some cyanide, please!"...The pharmacist, looking quite shocked responded, "Ma'am, I can't give you any cyanide, what would you need it for?"...She replied "I want to kill my husband!"..."If I give you cyanide, I will lose my job...and you will go to jail for killing your husband..I can't do that"....She opened her purse and took out a photo and handed it to the pharmacist... a picture of her husband ...in bed....with HIS wife...He looked up and said..."Why Ma'am, you didn't tell me you had a prescription!!!"
