The short anime comedy Bureau of Proto Society takes us to a post-apocalyptic bunker, when the last remnants of humanity live isolated from the world. The bunker’s historians gather each day to try to debate how the world ended—and once you see their historical sources, you’ll understand their confusion.

Sadly, this short, by writer/director Yasuhiro Yoshiura (Patema Inverted) isn’t embeddable, but you can watch it at the Japan Animator Expo website, where it will be available for the next few weeks. (Click the English flag in the upper right hand corner if you don’t speak Japanese and be aware that theres a minute-long opening before the actual short starts.) It’s a very funny film, packed with pop culture references, and snazzy ending.
