The name belongs to an Old Testament object that served as an oracle to Aaron, Moses' brother. The Book Of Mormon "author" Joseph Smith also claims to have come into possession of it.
So, fast forward too many centuries to keep track of. Three native Tennessee Everymen are on their way to Nashville for a tiling job. They enter town late and decide to blow off the job and go to a local Goodwill store. One of these men finds an unusual object lying on a self in the housewares area of the store. He lays out sixty nine cents for it.
He claims this object is the Urim and Thummim.
See for yourself.
I recently had a chance to see the documentary, where I met the director and the three gentlemen featured in it. I also had my chance to look into the "object." That, gentle readers, is a story for another day.
