'THE WILD, WILD WEST'
"THE NIGHT OF THE HOWLING LIGHT"
When Dr. Arcularis said that he was going to take the lessons learned from recent experiments on mice and apply them to human subjects, Secret Service Agent James West pointed out that mice weren't exactly the most intelligent species on Earth.
Over a century later, at least two humans from that same planet learned that mice indeed were the most intelligent species on Earth.
Mice are the physical protrusions into our dimension of a race of hyper-intelligent pan-dimensional beings who commissioned construction of the Earth to find the Question to the Ultimate Answer of Life, the Universe, and Everything. As such, they are the most intelligent life form on that planet, contrary to what humans think.
