A chat transcript (post format Chat), like so:

• Lady: I would like to buy some cyanide.
• Pharmacist: Why in the world do you need cyanide?
• Lady: I need it to poison my husband.
• Pharmacist: Lord have mercy! I can’t give you cyanide to kill your husband.
• Lady: Owh yeah?!? Check this out! (The lady reached into her purse and pulled out a picture of her husband in bed with the pharmacist’s wife.)
• Pharmacist: Well now, that’s different. You didn’t tell me you had a prescription.
