In A Bug’s Life, the circus ringmaster is a flea. It’s a flea circus.
Admittedly I had heard the term “flea circus” my entire life but only this morning looked up what it actually was. I mean it’s pretty straightforward, a bunch of fleas made to look like they’re in a circus, but I was missing the history and context.
In the original Fallout I was quite proud of myself for picking up on the fact that Dogmeat was a Road Warrior reference.
It took me years to realize that the leather jacket and (to a lesser extent) sawed off shotgun were also riffing directly on Road Warrior.
