Illogic

Illogic

Xog and Xig carefully piloted their currently invisible spacecraft into the shopping mall parking lot. They had been sent to Earth to prepare a report on the degree of human civilization.
While Xig programmed their spacecraft to disguise itself as an Earth vehicle, Xog exited the spacecraft and looked around.

On the first building that Xog saw was displayed "Human Services".
Excitedly, Xog called Xig. "Xig! Look at that. What do you think of it?"
Xig looked toward the building. "Yes, one favorable mark for humans for our report."
"Favorable! Why favorable? Xig, don't you see? This sign shows that they are discriminating against nonhumans!"
