A double rainbow

There is some sort of commercial running now - for the lottery, maybe? - that has a guy exclaiming over a double rainbow. I kept thinking: where have I seen this before? Here. The original goes on for about 8 minutes, and the guy laughs, weeps and appears to reach orgasm. I will spare you that version. I can't find the ad anywhere, but this was posted 6 years ago and there have been lots of parodies.
