Achilles' vent

In the first of the Futurama movies, "Bender's Big Score", in order to take Earth back from the naked, scamming aliens who scammed the Earthicans out of it, the Earthicans, who took refuge on Neptune had to fight an army of golden death-stars. In this effort, Al Gore destroyed one by flying through a vent, labeled "Achilles' Vent".
