I love pet rocks! I actually bought one at a hobby store as a kid -- that was my purebred. He came with blanket and a brush and a little bottle of rock shampoo (I think it was really Johnson's baby shampoo). My mom wanted to know why I kept bringing in rocks from outside if I already had one inside. I told her, "Oh, these are strays and they need a good home". That was fine, but she wasn't happy when the washcloths turned into beds for my "pets".
