A woman went into a pharmacy and looking straight into the pharmacist’s eyes said, “I’d like to buy some cyanide.”

“Why do you need cyanide?”

“I going to poison my husband.”

The pharmacist exclaimed, “I can’t sell you cyanide to commit murder! I’ll lose my license and they’ll throw us in jail! Absolutely not! You CANNOT have any cyanide!”

She smiled and showed him a photo of her husband in bed with his wife. 

Looking at the picture he smiled and said, “Well! You didn’t tell me you’d got a prescription.”
