John:
I really believe that we’re not compatible, from a standpoint of having common interests.  But in electronic terms, there’s a circuit in an amplifier called "push-pull."  The final stage is called "push-pull."  They’re not the same, but one of ‘em pushes, and the other one pulls.  You know, so this is the way that the amplifier operates at the output stage.  And I always view a couple, a marriage couple, in this kind of a sense, because I know this amplifier works, I know how it works, and I can describe exactly some of the things that each portion of this—it doesn’t call it a male and female, but it has opposite characteristics.

RF:
They’re just complementary and—

John:
Yes, and that’s exactly what it’s called.  A complementary pair.
