Double rainbow all the way

I can't really account for why this video is so good, but let me tell you, there's a compelling reason why it has had 21,540,032 hits on youtube and been such a widespread meme.
Long story short, this guy- hungrybear9562- is out in the mountains, presumably tripping balls, and sees a double rainbow and goes from appreciation and wonder, through to near orgiastic rapture to sobbing in the 3:30 span of the video and it makes me lose it laughing every time!!
