Celebrated Goosebumps author Stephen King churned out a new book, Under the Dome, which features a town encased in a giant dome (possible metaphor???), which The Internet immediately declared to be a rip-off of The Simpsons Movie, which was of course the first movie to feature a dome. King denied these grave charges of plagiarism, claiming to have come up with the plot when he started the story in the 1970s, which pre-dates The Simpsons by a week or two. He further attempted to prove his innocence by scanning the first 60 pages of his manuscript, typed out in their original IBM typescript, which should erase any lingering doubts because faking old typewriter fonts is impossible.
It should be noted that even if King ripped off The Simpsons Movie, The Simpsons Movie is itself a rip-off of Neon Genesis: Evangelion, so uhhhh double jeopardy?? [The Independent]
