Source of GR-Related Poem

[Coffey, Mitchell R]

I found the following poem anonymously felt-penned onto a wall in the
Bancroft Library on the UC Berkeley campus, c. 1977:


	Slim Pickins rode the bomb down laughing
	Bucking to oblivion
	In gravity's rainbow rodeo

Does anyone know the source of this work?  I don't believe it's from GR
itself; I've only got the book partially memorized, as yet, so I could be
wrong.
