There is a scene in the 1989 cult classic Bill & Ted's Excellent Adventure in which various historical figures, from Billy the Kid to Abraham Lincoln, find themselves thoroughly out of their depth when they are transported to 1980s California.

We see Beethoven testing out the latest electronic keyboards in a musical goods store. We see Joan of Arc forcibly taking over an aerobics class. We see Genghis Khan scrapping with security guards in a mall. And throughout all of these scenes, we are drawn in simply by the peculiarity of seeing figures from the past in the context of the present.

Watch just ten seconds of an M-1 Medieval fight – where the modern MMA ring anachronistically plays host to men dressed as knights from the Dark Ages – and you will get this very same feeling. Only this time, it won’t be part of some goofy, off-beat '80s movie. This time it's real.
