This is actually from the Cosmic Wheels Album.  Got to see him do this during the Cosmic Wheels tour back whenever.  A great silly little ditty.

I first heard this song when I was visiting relatives in Norway. A group of us had gone up into the mountains to chop wood for the winter. When we were sitting in the cabin listening to the radio (all in Norwegian), suddenly The Intergalactic Laxative came on and we all sat listening to it and laughing.
