I heard a joke once: Man goes to the doctor. Says he’s depressed, life is harsh and cruel. Says he feels all alone in a threatening world. Doctor says, “treatment is simple. The great clown Pagliacci is in town. Go see him. That should pick you up.” Man bursts into tears. “But Doctor” he says, “I am Pagliacci.”
I know it relates but the source is wrong, this is an Alan Moore quote, more specifically from his character Rorschach from Watchmen.
