I found this thing on the internet that creates crossover fanfiction ideas for people who can't think of a topic to write about. or if you're too lazy to think of a regular topic or crossover yourself It's called kaction and it comes up with great themes and plot devices such as "Your challenge is to write crossover fanfiction combining Neil Patrick Harris and Metallica. The story should use getting sucked into the "real world" as a plot device!"

excellent. Also, I couldn't really find somewhere else to put this and I thought that it could be a challenge (as it says "your challenge is" when it generates something). also this is a feeble attempt to revive this Also, it can come up with some weird things, so you might want to click the title again if you get something too weird... *ahemcough*
