A woman walked into the pharmacy. She walked up to the counter and looked the pharmacist straight in the eye and said, "I want some cynanide". "That's an odd request", said the pharmacist, "how much do you need?" "Enough to kill my husband" replied the lady. The pharmacist was dumbfounded. "You can't do that! You don't just go around poisoning people. You'll have us both put in jail!" The woman reaches into her purse and takes out a picture which she puts on the counter. It's a picture of her husband in bed with the pharmacist's wife. "Oh" said the pharmacist, "you didn't tell me you had a perscription."
