As far as we know, there are only taco bells on the planet earth. As far as we know, taco bell is only a taco chain not a secret society masquerading as fast food taco restaurant. As far as we know, taco bell did not organize the JFK assassination. As far as we know, taco bell was not used to feed POWs during WW2. As far as we know, taco bell is not the public face of the order of the taco, a global shadow government that has ruled the realm of man since the dawn of time, deciding who wins wars, who develops technology, and who wins elections.
Given the incomprehensible vastness of the universe, it’s the height of arrogance to assume that Taco Bell has not arisen in other star systems. The only thing doubtful is that extraterrestrial Taco Bells have visited Earth.
Just tried using Google Earth to check for any Taco Bell locations to confirm this. How convenient that it wouldn't let me look anywhere close to Mars. They're keeping something from us!
