A Sign of the Times

I've had repeated problems with who i call Door Christians. I resorted to putting a sign on my door to fend them off.
But my previous sign was not enough to deter these religious zealots who knock and want to share their myths with me.

Since I often sleep during the day, this is usually cause for great irritation.

I had to go to a sign that was more caustic.

{it's really harsh, but it still makes me laugh}.
