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." Man
bursts into tears. Says "But, doctor...I am Pagliacci."
