3. Ken Jeong is a certified doctor.
From cult shows like Community to big blockbusters like Crazy Rich Asians, one could say that this man has had a very diverse path toward stardom. But even if he doesn’t stay there forever, he can always support himself through his career in medicine. He has even practiced his medical skills whenever they were needed, like the time when he delivered emergency care for a woman who suffered an attack at a club where he was performing and assisted her while the paramedics were on their way.
