Brent Spiner says that he was too busy hitting on Klingon extras. When the girl walks away from Michael, he says that she was like a Deltan and a Betazoid all roled into one.
Michael also asks Brent what the Ferengi were like.
These are all aliens from the Star Trek franchise. Klingons are the warrior race with the forehead ridges, considered one of the most popular aliens in the series. Deltans are bald and emit pheremones that make them irresistible to humans. Betazoids are a race of empathic and telepathic people who look similar to humans.
The Ferengi are a race of merchants distinguished by their large ears and sharp teeth.
