The Grinning Alligator was a cast iron medieval torture device. Rocking it back and forth a few feet in front of a restrained prisoner's face, a Vatican-appointed Inquisitor would use a hidden switch (not visible) to raise and lower the upper piece, all the while chanting, "[I]nterior crocodile alligator, I drive a Chevrolet movie theater." This was often accompanied by a small choir and/or Papal dance troupe. Invariably, the victim would eventually be induced into a near-catatonic state, and with no further urging, confess to any number of alleged crimes.
