I've noticed that Jehovah's witnesses seem to go knocking on doors on Saturday mornings. It seems like a bad way to sell your idea to me, getting people out of bed.
I had a couple of Mormon's try to come in for dinner once. I was halfway through serving up when the doorbell went. Two chaps from Utah, telling me that I could have loads of wives and listen to the Osmonds forever after.
I said "Thanks for considering me for entry to your club, however I'm just serving up my dinner.". One of them said "Oh that's nice, do you have enough for us too?"...
The cheek. I was all ready to sign up before that. I bleedin' love the Osmonds, me.
I actually live next door to a Jehovah's Witness family. Really nice people, very straight-laced and family-oriented. They've never raised the matter of religion with me, either.
My father (traditionally-raised Catholic) saw them heading off to church one Sunday morning and said to me "Ah, I see your new neighbours are a good Catholic family"... Jehovah's witnesses wear smart suits and go to church early on a Sunday all as a family, large families etc, very similar stereotype really!
