Richards has stated that he and Jagger wrote the lyrics while staying at Richards' country house, when they were awoken one morning by the clumping footsteps of his gardener Jack Dyer walking past the window. Surprised, Jagger asked what it was, and Richards responded: "Oh, that's Jack – that's jumpin' Jack." The lyrics evolved from there. Humanities scholar Camille Paglia speculated that the song's lyrics might have been partly inspired by William Blake's poem "The Mental Traveller": "She binds iron thorns around his head / And pierces both his hands and feet / And cuts his heart out of his side / To make it feel both cold & heat."
