I found this interesting little tidbit on Mexican Day of the Dead traditions while browsing about:
"In each household, which is the center of the cult of the dead, it is believed that the souls of the dead have taken a journey to the world beyond. The souls of good people travel a straight and narrow path to another world, while the souls of bad people travel a wide and labyrinthine way. All souls arrive at a deep and broad river that can only be crossed with the help of a dog, which lifts the souls on his shoulders and carries them over to the other side. In Tlaxcala, at least, it is believed that the bad souls would be refused transportation across the river, while good souls could persuade the dog to carry them more easily if they had coins that were placed in the mouth or the hand of the dead at their funerals. In many communities it is believed that dogs must be treated well in this life because they are spirit helpers in the next."

Also in it seems the LDS church is up in arms over HBO's Big Love showing recreations of their temple ceremonies and have released a short video about their temples in response.
