The pageantry of the Third Reich and the precision of its army reached a dramatic climax during the festivities honoring Adolf Hitler on his 50th birthday: April 20th, 1939. This complete Nazi newsreel shows Berlin--adorned with flags and floral displays by its citizens and monolithic statuary designed by Albert Speer--preparing for the holiday. Scenes of throngs of Germans congratulating their leader are followed by a review staged by Germany's armed forces--the greatest military demonstration in the history of the Third Reich.

stupid drug related slang originating from a bunch of kids who used to get high and look for a field of marijuana way the fuck back in the 70s. for some reason it has perpetuated itself to the point where every dumbass who doesn't know fuck all about drugs adores it, while the left are wondering what the fuck is wrong with everybody
retard: oh my god it's almost 420!

smoker: 4/20 is bullshit. nobody who's really into drugs actually cares about it

retard: well then you must not smoke, because i know everything about drugs. i smoke purple haze and i planted hydro seeds in my yard

An incredibly idiotic holiday, usually celebrated by wanna-be potheads who think that he/she is cool.
However, some people just smoke during 420 because, hey, they want to get high.
So chances are, if you're celebrating that stupid holiday...you're pathetic. (unless you're the noted above)

I smoke whenever, because weed is great; anytime of anyday.
boy: "it's 420! i'm getting sooooo high!!!
me: "go lick a window, you stupid, poser, asshole."
