Since one of the founders of earth day was a murdering scumbag who pulled a Polanski, shouldn't earth day shirts be banned for the violent connotations?
The first earth day I was forced to participate in was on April 20th, for whatever reason. (I think the 22nd was on a Sunday that year) So I've always associated earth day with 420 and Hitler*. Yep, I was an ass about it in school. I think it was in 1990, as no earth day crap was ever mentioned up until the "20th anniversary" that year.
*Makes more sense to me that way. It is really just socialist propaganda invented by watermelons who drafted potheads as their "friendly faces" off and on through the years.
