There must be more than a few LOTR fans in my church. We have a wing in which the basement is about 6 feet higer than the basement of the rest of the facility. It is called "Middle Earth".
And our sound system console has a sign by the button that turns off the entire system without damaging or ruining anything. The sign says, "The One Button To Rule Them All - press this button and no other to turn off the system safely".
Just made me laugh when I noticed it this past week.
