It is the ultimate expression of contempt from an alien overlord, a hideous hellspawned demon or a powermad supervillain. Nothing else quite encapsulates the loathing they feel for all humanity like this simple phrase.

Rules for use:

A) Always start your tirade against the pathetic monkeyspawn of the backwater planet with this phrase, preferably in an amplified or other wise loud voice.

e.g. "FOOLISH HUMANS! YOUR PATHETIC WEAPONS HAVE NO HOPE OF DEFEATING ME!"

B) Never over use the phrase. Starting every explosive oration with it will sap its vicious edge. That, and the other overlords will mock your writers.

C) The key to the phrase is its mocking inclination. When a small part of your hideously complicated plan for world domination comes unraveled because of meddling teenagers or superpowered do-gooders, toss one off to show that you are still in control.

e.g. "FOOLISH HUMANS! YOUR TINY MINDS CANNOT BEGIN TO FATHOM THE WORKINGS OF MY PLAN!"

D) Last but not least, don't use this phrase on non-humans. It just makes you look stupid. If you can't take the time to find out the genus of the species you are trying to dominate, do everybody a favor and just blow up the planet.
