Heard joke once:

 Man goes to doctor. Says he's depressed. Says life seems harsh and cruel. Says he feels all alone in 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." Good joke. Everybody laugh. Roll on snare drum. Curtains.
