Knock on the door

[KWC]

There was a knock on the door this morning.
I opened it to find a young man standing there who said:

"Hello, Sir, I'm a Jehovah's Witness."

I said "Come in and sit down."

I offered him coffee and asked, "What do you want to talk about?"

He said, "Buggered if I know, I've never got this far before."
