First of all, it is well known to be when potheads get even stupider, but it has even more meaning. It's Hitler's birthday, and it's my Dad's B-Day too! Hmmm... coincidence? And it is a sweet type of boat. So us sailors can go around with 420 written all over shirts, bumper stickers, ect...

everyone's racing 420s this year

wtf? no, none of these potheads that "know what they're talking about" are right. April 20th is the best time to plant your seeds for pot growing season. your plant will get just enough sunlight just enough water. why would getting high be better on april 20th? why would smoking weed at 4 20 be better? its not, its the time to plant. know your shit.

hey im a dumbass i bet 420 means i smoke weed on april 20th.

hey im not a dumbass, im planting seeds on april 20th.
