Happy 4/20! Get a contact high from these TV shows and movies

Warning: You may fail a drug test just form reading this list.

Maybe friends used to get a contact high just from walking into your college apartment on a Saturday night, but you have long since retired the bong because you've got kids or a job where they hold random drug tests.

Or maybe you are a self-avowed square like me, who despite having graduated from a school with a place called Bong Hill, never danced with Mary Jane and who for a long time wasn't completely sure what the term 420 meant.  It's traced back to 1971, when a group of high schoolers from San Rafael, Calif., known as the Waldos,  agreed to meet at 4:20 p.m. with map in hand to search for a plot of marijuana plants that had been abandoned by its owner.

The notion of 420 as a countercultural holiday became a thing in the 1990s when a group of Grateful Dead fans posted flyers in Oakland, Calif., urging fans to light up on April 20 at 4:20 p.m.

We don't care where you fall on the pot spectrum.  We're here to suggest pot-themed movies and TV shows for just about every altered state:

If you want a classic with your chronic: Up In Smoke

Pot comedy got its start this 1978 Cheech and Chong caper, in which the comics unwittingly drive a "fiberweed" van built entirely out of hardened marijuana resin from Mexico to the USA while being tailed by an incompetent narcotics officer (Stacy Keach).

Watch Up inSmoke for free with your Starz subscription or rent on iTunes

If you want to see how much attitudes about marijuana have changed: Reefer Madness

Picture an after-school special with 1930s production values and you've got Reefer Madness, a black-and-white morality tale intended to scare youth away from experimenting with "the burning weed with its roots in hell"  — which, if you believed the film, might lead teens to commit murder,  suicide or order someone to play the piano as fast as possible. But by the 1970s, Reefer Madness came to be seen as a case study of everything pot opponents got wrong — and something unintentionally hilarious to watch while blazing up. It even inspired a 2005 musical parody starring Alam Cumming and Kristen Bell.

Watch Reefer Madness free Thursday on Fuse or its website at 4:20 p.m. ET (complete with commentary by comedians Nick Guerra, Justine Marino, Orlando Leyba and Dan Klein) or rent the movie on iTunes.

If you're going to be at it for a while: That '70s Show

Eight seasons' worth of basement antics from Eric Forman and his friends should be more than enough to outlast anyone's weed supply.

Watch That '70s Show on Netflix

"My hands are magical": Topher Grace as Eric Foreman in 'That '70s Show.'

If Sean Penn will always be Spicoli to you: Fast Times at Ridgemont High

If you're under 30, you've probably only ever known Penn, a two-time Oscar winner, as a Serious Dramatic Actor, having played a grieving father in Mystic River, a condemned prisoner in Dead Man Walking and a gay political icon in Milk. But Penn's big break came in this 1982 high school comedy, in which he played stoner dude Jeff Spicoli, whose worldview can be summed up thusly: "Surfing's not a sport, it's a way of life, it's no hobby. It's a way of looking at that wave and saying, 'Hey bud, let's party!'

Watch Fast Times at Ridgemont High free with your HBO subscription at HBOGo.com

Before he was a serious actor, Sean Penn was stoner Jeff Spicoli in 1982's 'Fast Times at Ridgement High, along with Anthony Edwards, left and Eric Stotlz.

If you want to feel alright, alright, alright: Dazed and Confused

Like Penn, Matthew McConaughey has graduated to playing Oscar-caliber roles— and thinking deep thoughts in Lincoln commercials. But the difference is that McConaughey still begins his Oscar acceptance speech by saying, "Alright, alright, alright!" And that unscripted line came from his very first scene in his very first movie: Dazed and Confused, the 1993 Richard Linklater comedy in which the unknown Texan played a 20-something who had nothing better to do than hang out with high schoolers on the last day of classes.

Rent Dazed and Confused on Amazon or  iTunes

If you like bromantic bud comedies: Pineapple Express

Up in Smoke may have invented the stoner movie genre, but this 2008 comedy starring Seth Rogen and James Franco as a process server and a pot dealer having a very bad night gave rise to an entire strain of marijuana. "As we were writing it," Rogen explained toCannabist (in 2014), we said, 'If we're ever at a weed store or buying weed and someone offers us Pineapple Express, we'll know we've made it!"

Watch Pineapple Express free with your Starz subscription or rent on Amazon or iTunes

'Pineapple Express': Just because you're paranoid from smoking a rare, potent strain of weed doesn't mean they're not out to get you.

If you still quote Chappelle's Show regularly: Half-Baked

Catch glimpses of Dave Chappelle's future greatness (including his Lil' Jon impression) in this 1998 comedy, which he co-wrote and starred in as Thurgood Jenkins, a research laboratory janitor who sells the pot intended for use in an FDA study in order to bail his friend out of jail. Eventually, Thurgood and his pot-selling alter ego, Mr. Nice, become a little too successful, incurring the wrath of the local drug dealer.

Rent Half-Baked on iTunes

If you've ever used the phrase 'Bye, Felicia': Friday 

Rapper Ice Cube and writing partner DJ Pooh set out to create a "hood classic," and they pulled it off with this semi-autobiographical 1995 comedy about two friends (Cube and Chris Tucker) trying to figure out how to repay their pot dealer $200 before 10 p.m. And one throwaway line — "Bye, Felicia"  — entered the popular lexicon as a way to dismiss annoying people. Not too shabby for your first major script. In 2015, Friday even returned to theaters for a special 20th-anniversary engagement on  — you guessed it  — 4/20.

Rent Friday on Amazon or iTunes

If you'd do anything to satisfy your munchies: Harold and Kumar Go To White Castle

Potheads are a suggestible lot. Mention any kind of junk food to them when the munchies are kicking in and they'll set off on an epic quest to find it. Such is the case for investment banker Harold (John Cho) and his medical school applicant buddy Kumar (Kal Penn), who see an ad for White Castle while getting stoned in this 2004 film and decide nothing else will satisfy their hunger but a bag of sliders — even if they have to survive a ride of terror with Neil Patrick Harris and hang-glide to get their hands on them.

Rent Harold and Kumar Go to White Castle on Amazon or iTunes; Comedy Central (9 ET/PT)

'Harold and Kumar' didn't get those White Castle burgers but the film did put Kal Penn, left, and John Cho, on the map.

If you want to get in touch with your inner child: Blues Clues

Granted, you'd have a more authentic THC-induced experience with Teletubbies (which, let's face it, only made sense to babies and stoners) but we're going to assume you don't feel like paying by the episode or season to toke along with Tinky Winky, Dipsy, Laa-Laa and Po. So save your money and watch Steve Burns try to figure out what his dog is trying to tell him.

Watch on Amazon Prime

'Blue's Clues': There's plenty of stoner humor to be found in Steve's never-ending struggle to understand what that dog is trying to tell him.

If you think it's fun to mix Mickey Mouse and marijuana: Fantasia

More than 75 years after its release, this animated classic, consisting of eight segments — including one on the history of Earth and another featuring Mickey as a sorcerer's apprentice — remains Disney's trippiest film, and the best companion for cannabis.

Rent Fantasia on Amazon

Stoners still love 'Fantasia' more than 75 years later.

If you like to combine your sinsemilla with superheroes: Chronic-Con Episode 420: A New Dope

Comedian and @midnight panelist Doug Benson has managed to milk two documentaries out of his marijuana habit: 2008's Super High Me, in which he took a cue from Morgan Spurlock and spent a month off of pot and the next on a lot of it, and 2015's Chronic-Con, in which he spends an entire Comic-Con stoned. And he may be onto something: being high would at least make it easy to stomach the exorbitant wifi fees at the convention center.

Watch Chronic-Con on Amazon Prime

If you're not into stoner culture but are curious about pot's (legit) medicinal uses: Weediquette

This Viceland documentary series hosted by Krishna Andavolu is a bit like HBO's Real Sports for pot. It addresses marijuana culture, business, science and legalization, but it also delves into the drug's therapeutic uses. In Season 2, the show tackled its applications for treating cancer and chronic traumatic encephalopathy. Season 3, which kicks off this week, will take a look at its prospective uses for helping people with autism.

Watch Weediquette on Viceland or  YouTube

If you like to contemplate the universe while high: Cosmos: A Space-Time Odyssey

At least you'll know you are high while watching Neil deGrasse Tyson ponder the mysteries of the galaxy.  As opposed to the time I nearly collided with Neil deGrasse Tyson while getting on the elevator at work and wondered if the cold medicine I was on at the time was messing with my head. (Thankfully, we had photographic evidence of his visit, proving that I did not hallucinate the whole thing.)

Watch Cosmos on Netflix

Wow, man: Neil deGrasse Tyson stares into the 'Cosmos.'

If you are so stoned that you can't remember your Netflix password: Dark Side of the Rainbow

Kids today don't realize how easy they have it. Back in the day (that would be the early 1990s), you needed two people to watch the original mashup: one to man the VHS player and start The Wizard of Oz while the second started the recording of Pink Floyd's Dark Side of the Moon at precisely the right second.

Now all you need to watch the scarecrow dance to Brain Damage is this YouTube link. Where's the sense of accomplishment in that?
