So the ghost on supernatural was called Shojo today. A japanese ghost that you could only see if you were drunk. So as you probably know shojo is a type of anime/manga targeted to young women (who also watch supernatural due to the male leads) so I guess the idea here is you have to be drunk to like shojo? I don't know..they had to kill it with a samuri sword blessed by a shinto priest. I think they did something with anime before though I am not sure. Either way rather hilarious.
