I have always thought the fact that 4/20 (what we all know as the day to do nothing and sit in the park and smoke weed day) is so close to Earth Day could be no coincidence.  Official celebrations for earth day are two days away, but that means nothing.  Many are celebrating today because it is a weekend! 

 Weed is a plant, from the earth, and we are celebrating the Earth and all it has given us, right? Yah mon.  So smoke up friends, it's a beautiful day outside.
