TimexMarty knew, he went forward and backward in Timex. Flinstone and Rubble digging Pappy in a replica Earth at the corner of the Parthenon and that big red leafed tree on the real earth sitting just beside the wood shed where the Cherry tree blossoms grows and where the Lucid is parked. No doubt Marty went to the mall and bought a bunch of Tulips in celebration of nothingness and the emptiness of all that is glorious.
