Steve, I always wanted to do something similar to the signs in front of local synagogues some years ago that said:

Save Soviet Jews
(Redeemable for cash prizes)

Or

Free Soviet Jews
(With fill up of ten gallons of more?)
I could have gone up and seen if they had any in my size, but I wisely didn'.

But my favorite denomination name to see on the signs outside their church was


Assembly Of God
(Batteries Not Included)
My favorite one of those churches was fairly close to Manassas Virginia and was the Bull Run Assembly of God. The sermons, I would imagine, would be quite interesting and colorful.

I will leave the writing of graffiti to others. I will just imagine some very now and then.

And, oh yes, I learned it as "puts his money in the First National Bank" on the playground and started hearing "Moses Invests" tacked on to the end in the late 1960s.
