That is very annoying. He should not be there. How the heck am I supposed to fit that into canon? Unless.. Star Wars premiered on earth in the Trekiverse just like it did here and having him in the bar is just some kitschy antique decoration. I suppose this works, after all they obviously still had the Beastie Boys etc.. it's kind of weird though as it would mean my other universe is a fictional story in this universe..
Keenser makes a sighing noise just like R2D2 does when disappointed.
