That guy had to go to the effort of acquiring the tray and then painting it (though he seems to have weirdly forgotten to slap a "Pac 12" sticker on it). For what? Sacrilege for it's own sake isn't funny or amusing. It's not persuasive of anything. All it does is say "not only am I not Mormon, I enjoy mocking what they hold sacred." It's not the most offensive thing in the world, but it still says a lot about that guy and his friends. And about the athletic department, who never do or say anything about stuff like this.
