I was walking down the street and I saw a really creepy clown smiling at me. I got so scared.
Oh man.  Now I am having images of the movie "It" in my head.  What did you do?
I just ran home and hid underneath my bed. I looked out the window and it was on the street still staring at me. Now I can't leave my house!
That is unusual behavior for a clown.  I would say you might want to call the authorities.  There has to be a law against a creepy clown stalker
