Aye, probably. I haven't seen (or read? I think it's a book as well, but I might be thinking of something else) Psycho, but I think there was a Marie Antoinette reference on another floor ("Let them eat cake!"). I'm sure this has been mentioned before, but I couldn't find anything in a search.
Edit: We now have a general thread for all allusions. Please continue your discussion - if you so wish - there.
