A Jehovah's Witness knocked on my door yesterday, so I answered it and asked if he wanted to come in. He said, "Yeah, okay." I said "I'm just making a cup of tea, do you want one?" He said, "Yeah, sure." I said, "I've just made some toast do you want a slice?" He said, "Yeah, why not." We sat down and I asked him, "So what now?" He said, "I don't know, I've never got this far before!"
