"A equals X," says Mister One. br "A equals B," says Mister Two. br "A equals nothing under the sun br But A," says Mister Three. A few br Applaud; some wipe their eyes; br Some linger in the shade to see br One and Two in neat disguise br Decapitating Mister Three. br br "This age is not entirely bad." br It's bad enough, God knows, but you br Should know Elizabethans had br Sweeneys and Mrs. Porters too. br The past goes down and disappears, br The present stumbles home to bed, br The future stretches out in years br That no one knows, and you'll be dead.
