I am a blue rectangle Think sky, in a cramped box Think no frills convict overalls Think bluebird road kill My neighbours, the Whites, Are exciting as lavatory tiles As an undertaker's napkins As steamrollered ghosts We all play second to General Red Who hog most of the picture Who elbows us out of the frame He is the colour of Mars Of blood and thunder Of tubercular spit I am a blue rectangle I have no desire to be A squirt of octopus ink A pool by Hockney A toad's drool I would make An excellent Inuit's sideboard A smurf's nail file A ruler for a British admiral
