"This is the monolith from 2001"
And here we go again! We move onto Christopher Returns (s1:e15) and, again, not a usable literary reference in the entire episode! Because Lord knows BearAllen ain't reading The Compact Oxford English Dictionary. Per my very first post, this falls into the textbook category.
So, moving on! AGAIN!
Here's a scene. Watch the episode in its entirety if you want to see Strobe and Francine being heinous people, Lorelai and Christopher revisiting the spot of Rory's conception (in the biblical sense) and Lorelai performing a "ratty transgression" against Luke.
