Because they don't like random people knocking on their doors
A door to door salesman!
By opening the door.
Thought of this one on my own while playing WoW a couple days ago and I'm pretty sure it hasn't been told before. I like corny jokes. I Googled it and didn't find anything (:
A PDFile.
Because HE is the one who knocks.
Because to them it's boring.
My favorite is: "There's a maniac living in our neighborhood. He goes house-to-house leaving severed body parts on the doorstep. He gives me the willies."
Better grip. Happy Halloween :)

There's none. They both knock on the door, but never goes in!
That I will open the door
You let it sink in.
The mafia doesn't like witnesses.
