I heard the story of a doctor from China who picked up a psychiatry position at the hospital here; she'd never been to the States before but during her interview her English had been pretty good. So they hire her and give her some patients and she starts by prescribing some pretty strong antipsychotics for someone who doesn't appear all that sick. When the higher-ups question her, she explains:
"The patient has severe somatic delusions. He claims to have butterflies in his stomach. Also, he says he ate a submarine yesterday".
It sounds like one of these urban legends, but I heard it from a doctor who says he witnessed the conversation himself. Doesn't exactly inspire confidence in the system.
