Rocky Raccoon checked into his room
Only to find Gideon's bible
Rocky had come equipped with a gun
To shoot off the legs of his rival

My guess is, more GHGs are emitted in the production of a single copy of a thick-papered, glossy-printed "Inconvenient Truth," than in a few thin-papered, colorless copies of Gideon's Bible.  But really, it is a difficult thing to measure, once you realize that the Gideons want to put a copy in every unit in every hotel everywhere.

As for "Rocky Raccoon": The couplet always struck me as heartless, especially as Paul McCartney so lightly sings it:

<<
Her name was McGill; she called herself Lil;
But everybody knew her as Nancy.
>>

Maybe that was the point; maybe Paul wanted precisely for me to hate him, because he sang that lyric as he did.  Art can include an artist's sacrificing himself.

Chickens deserve our true friendship! So do fish! So do other sentient beings! Let us learn to be kind.
