- Bob Marley's birthday is on 4:20. LOL, I argued with my friends so much becaues they insisted this is right, then we researched marley and sure enough I won the argument:smokin:.

- The L.A. Police force's code for a marijuana offence was a 4:20 (first one I heard).

- Bob marley died at 4:20

- It's a day for dopefiends to celebrate Hitlers birthday, HAHAHA no shittin' I actaully heard this once.
mrdevious Reviewed by mrdevious on . What's this 420 thing all about then? Hello and welcome to my 420th anniversary thread, it is exactly 420 posts since I joined cannabis.com! I've decided to mark this day by turning my avatar upside down, for a period of exactly 420 hours from now. MY avatar will be restored to its uprightly splendour on the morn of the 1st of July. Anyway, I'd like to know why I am celebrating the number 420, can someone please explain to me the relevance of the 420 thing. What is it, 42 multiplied by 10? 4 and 20 blackbirds baked in a pie?
