Bush Tetras: Too Many Creeps (Link)

Note:  Pictured in positions (1) and (2) above are representations of types of "creep."  Image no. 3 is a "creep machine."  The Bush Tetras song is for the ages.  Readers will have no trouble summoning and adding their own mental images of other creep forms.  Like rust, creep(s) is/are everywhere.  No sleep for creep.
