[MisterGreen]

Its what like 10 people said in the last "origins of 420" thread. I assumed it was correct, guess it isnt.

Oh, that's ok then. It's those other idiots filling the world with force information!

i found an article on this that listed over 100 valid meanings behind this, but the one most widely accepted is the one mentioned above about the kids at school.

the Waldos are well known and definetly the most likely answer.

Im sure lots of stoned kids came up with theyre own stoned theories and as it was passed through the grape vine people began to say it like it was a fact.

Like the police radio thing for example
