There are all sorts of strange characters who exist within the Star Wars universe. Wookies, Ewoks, and whatever Jar-Jar is are all very unusual. It should come as no surprise that another character is just a grown adult wearing dinosaur pajamas.
When Knight Rider first came out, people were impressed that it had a talking car. But for some reason, people ignored the fact that it also had a talking human dinosaur. Some people are just really difficult to impress.
Everyone remembers NWA members like Dr. Dre and Ice Cube. But people always forget the contributions made by their least heralded member, Lorenz the Dino. He was even edited out of the Straight Outta Compton movie. That's just wrong.
In his spare time, Lorenz apparently enjoys shaving the legs of Victoria Beckham. It may seem like a weird thing to do, but it gives his life variety. In fact, he first got into doing this when he was encouraged to "Spice Up Your Life."
Looks like Doc and Marty went too far back in time, and then brought a dinosaur back to 1985. That can't be good for the space-time continuum. If there's a dinosaur version of Biff who somehow became a multi-millionaire, now we know why.
If you've seen The Social Network, you know you don't get to 500 million friends without making a few enemies. And you don't get to 500 million friends without one of them being a dinosaur. Just based on percentages, it was bound to happen sooner or later.
Remember at the Oscars when Ryan Gosling handed shoes over to that dinosaur guy sitting next to him? Most people didn't even seem to notice. Probably because we were all too busy getting lost while staring into Ryan's eyes.
