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.
