A lady walks into the drug store and asks the Pharmacist for some arsenic.
The Pharmacist asks, Maam, what do you want to do with arsenic? The lady says, Kill my husband.
I cant sell it to you for that reason says he Pharmacist. The lady reaches into her purse, pulls out a photo and hands it to the Pharmacist.
The photo is of a man and a woman in a compromising position. The man is her husband and the lady is the Pharmacists wife. He looks at the photo and says, Oh, I didnt realize you had a prescription.
