It’s time to play doctor!
She dropped out of dental school halfway through, and "Dr." Vinisha Sharma had no license, but she practiced as a dentist in the UK for nine years. She did have the letters "BDS" (Bachelor of Dental Surgery) on her personalized Mercedes license plate.

"Dr." Mika Jokinen, 24, was a "doctor" in Finland who forged documents and practiced for a year. He had no medical training, and was caught because of "uncertainties" in some of his treatments. He said he needed the money.

At a Miami Florida spa, "Dr." Ana Josefa Sevilla pretended to be a plastic surgeon and, to improve its appearance, injected silicone gel and saline into a woman’s buttocks. The women needed emergency surgery and almost lost her leg.

A woman, happy to have married a doctor, dropped him off at work every morning. Then she discovered that nobody at the Atlanta Georgia hospital knew "Dr." Eric Perteet. After being arrested with a stolen security badge with his picture scotch-taped on top, he continued to insist he did work at the hospital. Later, he admitted he impersonated a doctor to meet women, and was having an affair with a woman at the hospital.
 "Dr." Daniel Ray Stewart spent two weeks in the emergency room before someone noticed he didn’t have a badge. "Dr." Stewart said he was only shadowing doctors and nurses, and if the hospital thought something was wrong, they should have let him know instead of going to the police: "My job is to observe and be a helping hand if needed and to further medical assessment." A hospital spokesman said he is "a troubled young man."
