So today is April 20th. For some, that means Easter. For others, it means… something a little different. And if you’re like me, you might be wondering what kind of cosmic joke lined those two things up on the same date this year.

But jokes aside, let’s talk about 4/20. The date has become a kind of unofficial holiday—a day for folks who enjoy the greener things in life to light one up and chill. I’m not here to tell you how to live, but I do think it’s worth knowing the real backstory behind why April 20th is so closely associated with weed.

Turns out, it has nothing to do with police codes, Bob Marley’s birthday, or the number of chemicals in cannabis (and yeah, those are all popular myths). The real story goes back to a group of high school kids in Marin County, California, back in 1971. They called themselves “The Waldos,” and they used to meet after school—specifically at 4:20 p.m.—to go searching for a rumored hidden pot crop. They never found it, but the code stuck. Eventually, it caught on with the Grateful Dead crowd, then High Times magazine picked it up, and boom: 4/20 became a thing.

And while we’re on the subject of things that became a thing, I decided to celebrate this afternoon by revisiting one of my favorite time-capsule films: Dazed and Confused. If you’ve never seen it, it’s a rite-of-passage kind of movie. If you have, you already know it’s a stoner classic that somehow manages to capture every version of high school—whether you went in the ’70s or the ’90s. Hell, even now, there’s something universal about it.

I’d forgotten just how many soon-to-be-famous people are in that movie. Ben Affleck shows up as the paddle-happy senior O’Bannion, and it’s wild to see him in such a meathead role when you know where his career ended up. But the one that completely threw me was Cole Hauser—yep, that’s right, Rip from Yellowstone. Back in the day, he was just Benny, another senior jock in tight jeans and cowboy boots. If you only know him as the grizzled badass on a horse, go watch Dazed and Confused. You’ll do a double take.

Fun fact: that might’ve been one of his very first film appearances, shortly after School Ties. Either way, it’s cool to see where people start—and how much can change with time.

So yeah, it’s 4/20. Or Easter. Or just Sunday. However you spent it, I hope it gave you a minute to slow down, laugh a little, and maybe revisit something that reminded you where you came from.

Because whether it’s a stoned high school parking lot in 1976 or a pot-smoking cowboy in modern-day Montana, everything starts somewhere.
