Episode 10 of Season 9 of Doctor Who, Face the Raven, had a funny easter egg. On a secret street in London where a variety of aliens find sanctuary one can find a mash-up of alien culture strewn about. On one wall was a collage of posters. One poster had what looked like a vague symbol that resembled the Flux Capacitor from Back to the Future. Confirming this, written along the side of the poster was an alien language. Just so happened to be the written language of the Star Wars universe, Aurebesh (created by the 1980s and 1990s RPG, see this post for more about that!). What was written in Aurebesh is the word DELOREAN. Neatly tying the time travel series with the time travel series, Back to the Future and Doctor Who, with a bit of Star Wars on top.
