Are you sure that your doctor is a real doctor? It can be difficult to tell! For example, if he gives you a bottle of pills called "Prosperous Farmer Dietary Supplements" that expired in 2002, he is probably not credentialed.

There are, in fact, any number of warning signs in this story of the Illinois gentleman who, responding to an ad in a Bulgarian newspaper, showed up to a clinic in late April:

The building appeared to be closed, though, with no other patients or employees around, except for the "doctor," who was dressed in a white lab coat, police said.

The "doctor" conducted an exam on the man and stuck toothpicks in his chest. He told the victim to take pills called "Prosperous Farmer Dietary Supplements" each day until the bottle was finished — though the expiration date on the bottle was February 2002, police said.

Can you spot them all? Here's one: When the guy returned with his son, the doctor "ran out of the building, locked the door behind him and ran eastbound on Golf Road." Everyone knows a real doctor would have ordered more tests! Hey-o!
