Jehovah's Witnesses

I used to just say thanks but no thanks and then shut the door.............
My wife on the other hand loves to let them start their pitch and then she acts overly excited and says something like "oh, you want to talk about religion?......you must come to my church this Sunday and meet pastor Andy" and then proceeds to act like a crazy lady going on and on about her church etc etc.............they always look at each other like WTF, and politely excuse themselves.
