Here's something I found elsewhere that is worth AN ENTIRE THREAD of crossovers that should not be.
http://kaction.com/badfanfiction/]The Terrible Crossover Fanfiction Idea Generator. And they're done as challenges!
For example, the last three attemps came up with:
1. Your challenge is to write crossover fanfiction combining Harvey Birdman and Neon Genesis Evangelion. The story should use furries as a plot device!
2. Your challenge is to write crossover fanfiction combining Spiderman and 4chan. The story should use anorexia as a plot device!
3. Your challenge is to write crossover fanfiction combining Big Brother and The Powerpuff Girls. The story should use someone opening a gate to Hell as a plot device!
