The much buzzed-about Riverdale flashback episode has come and gone, and it definitely did not disappoint. 

Titled "The Midnight Club," the episode gave audiences a peek into the lives of Riverdale High's parents when they were teens. What made it extra delightful? The present-day Riverdale crew played their elders, and we learned just how connected these two generations really are. 

And for pop-culture aficionados especially, the entire episode is an absolute must-watch. It's filled with nods to some of the most iconic films and TV shows from the 1980s and 1990s. Which ones did you catch? (Beware, some spoilers are ahead!)

1

Fans of Riverdale know that when it comes to this show, there's no such thing as a plot line or character back story that's *too* over-the-top. 

2

The soapy teen drama is all about unexpected twists and turns and keeping viewers guessing at all times. 

3

The most recent episode dove even deeper into the mysterious pasts of Riverdale's parents. And it was...intense.

4

For starters, the Riverdale crew from present day actually portrays their parental counterparts. 

5

Lili Reinhart's turn as Young Alice was a notable fan favorite. 

6

And people were really digging Cole Sprouse as a Young FP.

7

What also made this episode so epic? It was overflowing with pop-culture references from the '80s and '90s. Take, for example, the title, which is an obvious tribute to The Breakfast Club.

8

And Anthony Michael Hall, who played Brian Johnson in The Breakfast Club, even makes an appearance in the flashback episode as Principal Featherhead.

9

The title card was instantly recognizable for fans of the classic high school sitcom Saved by the Bell. Why did we ever stop using those brightly colored geometric shapes and squiggle lines, anyway? 

10

And KJ Apa's Young Fred is pretty much an exact lookalike of Luke Perry during his 90210 era. The hair, the jeans, the aqua-colored button-up. So iconic. 

11

The similarities had fans pretty shook. How are they not related in real life?!? 

12

Oh, and the parents also got buzzed on a drug called "fizzle rocks," which is definitely a reference to the Pop Rocks candy that all us '90s kids couldn't get enough of back in the day.

13

And the cherry on top of the sundae? The nonstop '80s hits, like "Take On Me" by A-ha and "Modern Love" by David Bowie, that fans were totally loving. 

14

To sum it up, Riverdale completely nailed the nostalgia vibes. As if we expected anything less.
