A nice bit of Fridge Brilliance from Star Trek Into Darkness: It took this troper a while to figure out why the planet in the opening sequence was named "Nibiru". Nibiru is the theoretical name for a rogue planet that the government is supposedly hushing up, due to its imminent collision with Earth. The connection doesn't become apparent until you remember that the movie's release date was pushed back to summer 2013 from late 2012.
Kirk: Nice going, Spock! We just saved the world!
