When my second cousin was younger my grandfather used to sit on the lid of the toilet and put the shaggy rug by the sink over his knee. He then used to open the door a crack and call my cousin and his sisters over to pet the carpet, calling it the 'dog', to see if they would actually believe him. His older sisters didn't fall for it, but for about three years he thought my grandpa had a shaggy white dog that lived in his bathroom that only came out when my grandpa called it.
Years later at my grandpa's funeral my cousin told the story as part of his eulogy-the priests were actually laughing hysterically.
