Ladies of 50,000,000 AD

The Ladies of 50,000,000 AD are the inhabitants of Earth in the year 50000000, a verdant paradise. They are very beautiful, dress in skimpy clothes and use negative mass neutrino fields for backwards time travel. Fry, Bender and the Professor encountered these women while searching for a backwards-traveling time machine. Fry and the Professor wanted to at least stay for their fertility banquet, but Bender (upset that they didn't stay in 10000000) reactivated the forward time machine.

Trivia

 * As they are almost all women, they value men regardless of age or intelligence.
 * Hold fertility banquets.
 * Can apply oil without using their hands.
 * A female dominated society could be based on the shrinking Y chromosome which will eventually force males into extinction.
