Nichelle Nichols' head is a character from TV Series "Futurama". She is a member of the Vice Presidential Action Rangers. Other members include Al Gore, Stephen Hawking, Gary Gygax, and Deep Blue. It is their duty to protect the fabric of the universe against disruptions. Since there is a space-time nexus at the point where Fry is frozen, it makes sense that Fry not getting frozen could start a reaction that could destroy the universe. Thus, in a what-if scenario, Al Gore and his Action Rangers must ensure that Fry is indeed frozen and sent to the future. Fry, however, not wanting to go to the future (after having seen "monsters" in a Fry-hole), destroys the freezer tube, and the universe disappears shortly thereafter.
