Today, of course, is the mythical 420, an underground holiday in which random people giggle into each other's reddened, dilated pupils, happy in the knowledge that they are completely and totally stoned. Snopes has the 411 on the day.

Ironically enough, today is also Adolf Hitler's Birthday, formerly a major holiday in Germany. Wonder what he'd think of his birthday being, if you pardon the pun, the High Holy Holiday of Potheads around the world.

Funny how the march of history goes, no?
