The Doctor is Doc (DOCtor?), Rory is Marty, Amy is Jennifer, K-9 is Einstein and River Song is Clara Clayton in this very clever animated mash-up of "Doctor Who" and "Back to the Future" by animator James Farr.
The "Sexy" license plate is a nice touch.
Either someone needs to let Farr run wild on a "Doctor Who" animated series or they need to get IDW on the horn and fire up a Who/BTTF mash-up in the comic series STAT.
