Broad City's world of series in-jokes and easter eggs
I like Broad City a lot, but I'm no die-hard fan. But maybe I might be if I re-watched several episodes. There seems to be a good amount of in-jokes, easter eggs, and callbacks in the show that make a TV series like this even more entertaining than it already is on the surface. Vox describes a few of them here in the video above.
