Searching for 420

What's the wierdest or funniest place you've ever seen "420"?

For me it was center field in Red Sox's Fenway Park. I've also seen this guy on the Price Is Right bid 420 dollars every time.

What the hell is this 420 thing?

It's a states thing.

national smoke day 4/20, april 20th. I cant recall any really weird places but it seems most of the time i see 420 is when telling time. I just notice it more that way

on my DL as my b-day...lol
