The Waldos
The Waldos™ all agreed to meet at 4:20 p.m. at the statue of chemist Louis Pasteur on the campus of San Rafael High. They met, got high, and drove out to search for the patch. In the ensuing school days the Waldos would use the term ‘420 Louie™’ to remind each other of their after school quest. They eventually dropped the ‘Louie’ part and just said ‘420’ to refer to cannabis. Originally ‘420’ was nothing more than the Waldos’ secret slang–their own private joke–, however, it was picked up by others and spread from generation to generation, city to city, country to country, across decades, and throughout all media around the globe." - The Waldos
