Plenty of those around. I'm remembering one of Kathy Reichs's YA fantasy novels in which the heroine, a niece of forensic anthropologist Tempe Brennan, whose adventures have been turned into the TV series Bones, sits down to watch Bones on TV. The author refused to discuss it when I asked about it at a session she did while in Melbourne. I think it was a promotional thing; she didn't expect anyone to say,"That doesn't make sense" and was probably hoping no one would notice, but might watch Bones. ;-)
