This happened at work today, via email:

Evil Overlord: For the information of all, here is the phone number to the M.E.’s office in case we need it for an investigation
Evil Overlord: For those who are confused, “M.E.” stands for Medical Examiner
Chief: Oh. I thought it was for the Medieval Executioner’s office. And here I thought my problems were solved. You don’t happen to have their number by chance? I have some business to throw their way.
Evil Overlord: Jacq does.
