The number silly, little teenagers talk about for days upon days, but do not get high when April twentieth is finally here.

April twentieth is also Adolf Hitler's birthday. This day is not commonly known as "420" when referred to Hitler's birthday, though.

There is belief that "420" is the police code for a "drug bust," but it is not. There are no codes for a "drug bust," only "drug deal," which is code "966."
