Ask her if she liked Digimon. If she did, immediately escape from this crazy bitch by any means necessary. I don't care if you've gotta wave down a news helicopter to lift your ass outta there.

Now, if she didn't like Digimon, try Beyblade. Because that show has to be the gayest shit in the world, and if she liked it... (please see above text). Now, I'm being serious here. Cartoons were a big part of childhood, and can tell you what kinda mindset the person you're talking to has. If she goes and says she absolutely loved Angela Anaconda, you know she's batshit crazy and will eat you alive when you sleep. There are others, but if she doesn't like any of those 3, you can assure yourself that she has a uncorrupted mind.
