Some people say it's "National Smoke Weed Day" or whatever. But it's actually Adolf Hitler's Birthday.

Teacher: 420 is Hitler's birthday if you didn't all know you morons.

when you ask a bunch of stoned youths what 420 means you may get some wild stories. from what i've heard the definition ranges from being as simple as date or time of day to having to do with spring/summer solstice and psychology. Don't tell me you haven't thought of that! trust me you did but you forgot (i love stoners like that). 420 means a time and day to get high, a code to meet friends to get high with, and a way of relating the positivity people that smoke weed possess and openly communicate. have a nice day.
my uncle says he came up with 420 when he was stoned but forgot to tell people
