Henry Kissinger's head

Henry Kissinger was the Secretary of State during Richard Nixon's U.S. presidency, where exactly he is in Nixon's Earth presidency is unknown, though he is described by Nixon as their "top peace negotiator". He was sent along with Bender Bending Rodríguez to end the war between Earth and Spheron 1, where they would meet with the Brain Balls to negotiate the peace. On enquiry by Bender about his suitability for the mission, Nixon described him with "looking like that, he talked his way into Jill St. John's bed. Nuff said!"

Given how Nixon sent Kissinger on a mission, which was planned to go off in a huge explosion, with the destruction of Spheron 1, along with Bender, the Spheriods and of course, Kissinger himself, Nixon doesn't seem to have a very loving relationship with his former Secretary of State. This may in part be because the exact person, he had to write his letter of resignation to, was Henry Kissinger.
