Bill Mack told this one on Willie’s Place Sirius/XM radio:
A woman went to a pharmacist and asked if he would give her some cyanide. “My husband is having an affair with another woman.”
The pharmacist said, “Oh, I’m sorry, ma’am. I can’t give you that. Cyanide is a deadly drug!”
The woman took out a picture of her husband in a compromising position with the pharmacist’s wife.
“Oh, I didn’t know you had a prescription,” he said, and filled her order.
