As told to me tonight by a haunt actor in his now 5th season.
He was dressed as a clown, pretending not to be a real person and not wishing to break character, he took a solid punch into his masked face, but began bleeding.
So he meanaced the puncher , who collapsed on the floor in a ball begging for forgiveness!
Mr. clown said something like:"I was told I couldn't punch back or touch you, so I won't."
Then he lifted his mask and alot of nose blood ran out, landing all over the cringing puncher/customer.
He also got kicked where it Really hurts by a girl.
Poor vision out of that mask and being too close to the customers were to blame.
