Funny joke

Man goes to doctor. Says he's depressed. Says life seems harsh and cruel. Says he feels all alone in a threatening world where what lies ahead is vague and uncertain.
Doctor says, "Treatment is simple. Great clown Pagliacci is in town tonight. Go and see him. That should pick you up."
Patient responds, "I tell you I think I'm falling into depression, and you tell me I should go watch a funny show? What sort of therapist are you? Are you even licenced?"
"Of course I am", doctor responds, sweating. He knows he will lose his licence if anyone discovers he is Pagliacci.
