From The Eponymous Flower:
"Some of us never take them off, not even in the shower. Who cares about stars anyway? Well, Mel Gibson is one of the most significant creative artists of our age, such as it is, and he's still got the Faith, even if he is a bit broken down inside. He still has a devotion to the Blessed Mother, the Carmelites and St. Simon Stock, and so should you.Link
After failing to appear at a press conference at the Cannes Film Festival for his upcoming film, "The Beaver", Gibson is depicted here wearing a Scapular, or a religious garment that consists of two brown pieces of wool attached to a string worn around the neck. From the looks of it, this is a really cheap one he's worn for ages, it's tied around his neck, the brown colored tag of fabric hanging down. It has an image of St. Simon Stock or St. Micheal the Archangel defeating the Devil, with an inscription which reads, "Whoever wears this scapular shalt not suffer eternal fire". It's a promise associated with the scapular that whoever wears it piously and follows its promises will be taken to heaven.
