I don't think I qualify as a real Fan sort of person, as I still don't know what the heck "jumping the shark" is. But I like you people, just judging from this one entry, the comments, and the pictures. Based on that data alone I would make your Mary Sue be a vegetarian orthodox Wiccan with a telepathic, giant, hermaphroditic 6-legged cat as her best friend and father/mother of her half-breed alien love child, as they grew up together on another planet when Mary Sue was kidnapped by aliens, but it all turned out okay, except for that asteroid accident that destroyed half her brain so she had to replace it with a supercomputer and now she is coming back to Earth and happens to run into you in the grocery store, where she realizes that you of all the people on the planet would be the perfect companion for her and Azathoth the cat-being.
