Lyric discussion by davidecoyote 

I once heard Billie and Mike came up with the name "Green Day" while watching an Ernie and Bert skit on Sesame Street. Ernie was explaining to Bert that it was green day, remarking on everything he could think of that was the color green. And I guess Billie or Mike thought of at least one more thing... So it kind of became a private joke between the two of them, a boring day where there's nothing to do but light up and get high. And it explains all the Ernie camios that pop up in their photos.

Of course I have absolutely no proof of any of this, but it's a damn good story either way.
