Taking Faith Healing Too Far

A faith healer asked Moshe how his family was getting along. "They're all fine," Moshe said, "Except my uncle. He's very sick."
"Your uncle is not sick," the faith healer said. "He THINKS he's sick."
Two weeks later, the faith healer ran into Moshe on the street. "How is your uncle getting along?" he asked.
Moshe shrugged, "He THINKS he's dead."
