A psychiatrist once had a patient who was complaining of despair.
"I'm so lonely", cried the patient. "My heart is heavy, I feel like I will burst into tears at any second. This depression grips me so that I don't want to leave my house, for facing people makes me feel like they are all laughing at me, and staring at me, and secretly plotting against me."
The psychiatrist thought about this for a while, then grabbed a pen and a piece of paper and started scribbling.
"I have the perfect solution for you", said the doctor. "The world famous clown Pagliacci is in town. He is amazing! he will lift your spirits and your heart will soar like a hawk in the morning sky. He will brighten you mood, and make you laugh like you have not a care in the world."
Whereupon the patient stabbed the doctor in the eye with his letter opener.
The moral of the story:
Clowns are Scary.
