420

Yes, it's true that the "Waldos" were some of the first people to coin the phrase 420, but, before the "Waldos" there was a band called, The Grateful Dead.

Supposedly, on April 20th (some year between 65' and 75') the band was trying to buy some weed. They put together all the money they had on their persons at the time, and it amounted to $420. On April 20th, The Grateful Dead bought $420 dollars of weed, and after they realized the coincidence, they decided that in light of the "herbal" phenomenon, they would smoke before any/every show, at 4:20 PM because most Dead shows started around 5ish. During the show, the Dead would entertain their audiences with stories about what happened before the show, or just any stories that they had. They would usually include any crazy "Trips" or "Thoughts" they had while they were high. Normally, in the middle of someone's story, another band member would chime in and say "Yeah, but you weren't feeling that way until 420". Once the hippies caught on, it was just a spiral Up from there.
Hippie A: Did you go to the show last night, man?

Hippie B: Yeah man, we even smoked with Jerry at 420! It was fuckin' sweet man!

So far the majority of you are incorrect.

420's origin IS known.

the term 420 originated at San Rafael High School, in 1971, among a group of about a dozen pot-smoking wiseacres who called themselves the Waldos, who are now pushing 50. The term was shorthand for the time of day the group would meet, at the campus statue of Louis Pasteur, to smoke pot. Intent on developing their own discreet language, they made 420 code for a time to get high, and its use spread among members of an entire generation.

So there ya go, someone's parents out there invented the term 4/20.
