Does anybody have/remember the words to the "Billboard Song"? It was about a windstorm which hit a signpainter's yard and created signs like "Simonize your baby with Hershey chocolate bars". If I remember the last verse was "If you want to make this world a better place to stay, just buy a copy of this song and throw it far away."

The other one I remember from about 1969 (when they used to introduce themselves as the "Smothers Brothers of the Stone Age" )was a parody of The lovin' Spoonful's "Nashville Cats" with a chorus of:

Nashville Cats - drive custom Continentals
Nashville Cats - got boats and airplanes too
Nashville Cats - play diamond studded guitars
Nashville Cats - they all got payments due.
