A little levity
For instance, Chapter 1 -- Lower Your Standards or Strategies for getting a date -- includes this advice:
Looking beautiful can be hard work, and sometimes the process isn't pretty. The Egyptian vulture is a very beautiful bird with fluffy white feathers on its head and shoulders, and a bright yellow face. It's the yellow face that other Egyptian vultures consider sexy -- the yellower the better. But how does a vulture get such a striking face? By eating the dung of cows, goats, and sheep, that's how.
Do yourself a favor; admire your date's good looks, but don't ask too many questions about her beauty routine.
