@Mum: I used to work at some Bethel branches and one of the jobs at one Branch was to open all the letters that arrived (job has to be done by a brother, sisters where not allowed to do so). I had to rip open the letters, separate by topics (departments) and if something looked "confidential" or had sensitive information it had to go directly to the Service Department Secretary.
Long story short. One person regularly used to send lottery tickets. Lots of times they where a couple of weeks old and already marked with "No winnings". I laughed my ass off, thinking why someone would do something like that. Maybe they thought that holy spirit could turn them miracously into winners. Or the person was totally nuts. Probably the last.
You would get lots of funny mail. Sometimes even letters addressed to Charles Taze Russell or Judge Rutherford!
