Yeah, I believe that one just like I believe ONLY Jehovah's Witnesses return found money!
Remember all those cheesy experiences at the conventions? The person who found the money (if you think this is a real story), would have to say in a straight face "do you know why I returned your money? Because I am one of Jehovah's Witnesses! - said in the most haughty, annoying tone ever.
I think someone should collect news stories of young ones who are not JWs and turned in lost money - and mail them all to the Society, postage due.
