Harold & Kumar Go To White Castle, Pineapple Express Harold & Kumar Go To White Castle, Pineapple Express

While the more ecologically minded might celebrate Earth Week by planting a tree, others might find other uses for said trees. Check out our top 10 stoner movie moments and then share your favorites in the comments below. [Warning: The following clips contain adult content, language and plants.]

10. True Romance
Before he was a Hollywood heartthrob, Brad Pitt had a small-but-memorable role as Floyd in the Quentin Tarantino-penned True Romance. As gangsters storm his home with guns a-blazin', he was still hospitable enough to offer them a hit off his plastic honey-bear bong.

9. Harold and Kumar Go to White Castle
Kal Penn's chronic-loving Kumar had a nose like a bloodhound when it came to his beloved bud. And yes, the man making love to a bag of weed in this clip is now working in the White House.

8. Fast Times at Ridgemont High
Sean Penn played a memorable toker: ne'er-do-well and occasional high school student Jeff Spicoli. How did he quell the munchies during class? Simple! He ordered a double-cheese-and-sausage pizza — to his desk. (Click here to watch the video.)

7. Cheech and Chong: Up In Smoke
Stoner-movie trailblazers (emphasis on blazers) Cheech Marin and Tommy Chong still hold the record for biggest blunt ever depicted on the big screen.

6. Pineapple Express
The only thing that gets more screen time than James Franco and Seth Rogan in this flick is the "dopest dope" El Niño could create. Fun fact! Producer Judd Apatow has said that True Romance's Floyd (see above) was his inspiration to make Pineapple.

5. Fear and Loathing In Las Vegas
OK, so it's not just wacky tobaccy that Johnny Depp is sampling as well-known indulger Hunter S. Thompson. But the sheer psychedelic awesomeness of Thompson's various trips (one of which also includes Tobey Maguire) meant we couldn't leave this one out. Just don't watch it when you're, well, you know. (Click here to watch the video.)

4. Friday
Smokey (Chris Tucker) is all about celebrating the start of the weekend with some herbal refreshment on the front porch. His motto: "Weed is from the earth. God put this here for me and you. Take advantage!"

3. Knocked Up
In a nice reversal, Ben's pothead friends' red-rimmed peepers aren't because they're stoned: They gave each other pink eye from farting, bare-assed, on each other's pillows. Well, except for that last guy. (Click here to watch the video.) 


2. Dazed and Confused
Saying that Wooderson is the best character Matthew McConaughey's ever played is not a dig at the actor; Wooderson is the best character anyone's ever played. Party at the moon tower!

1. Half-Baked
Jon Stewart explains why everything is better when you're high — "Ever see the back of a 20-dollar bill on weed?" he asks. And Dave Chappelle steals the show with his lame attempt at a Jamaican accent — "Lawdamercy!" (Click here to watch the video.)

Honorable Mention: Family Guy
While it's not a film, we had to acknowledge Sunday's Family Guy for getting a jump on 4/20. Stewie and Brian try to legalize marijuana in Quahog with "A Bag O' Weed," a cannabisized version of "Me Ol' Bamboo" from the musical Chitty Chitty Bang Bang. Who knew a bunch of bongs could double as a xylophone? (Click here to watch the video at the 10:02 mark.)
