Where are the Space Aliens?! (2010x109)

:

In which Hank takes on the Fermi Paradox. Why, if there are so many stars in our galaxy, have we not heard from inhabitants of other galaxies. Hank honestly believes that it is because we're stupid to think that civilizations communicate the way we do, think the way we do, or act the way we do. And if they do act in any of those ways, they probably won't do it for very long, because we probably won't do it for very long either.
