A group of engineers were debating about which animal is the fiercest. One engineer said the tiger is the fiercest animal. Another argued that the lion is much fiercer. Along came a marketing guy. He said, "You guys are all wrong. The fiercest animal is the Bipolar Bear." Everybody looked at him quizzically. "Yes, the Bipolar Bear is the biggest, meanest, orneriest, fiercest animal that is, and he has a head on both ends. That's why he is called the Bipolar Bear."Everybody shut up and looked thoughtful. Finally one engineer asked, "... but ... if he has a head on both ends ... how does he ... eliminate?" And the marketing guy said, "Well, he doesn't eliminate. And that is why he is the biggest, the meanest, the fiercest, the orneriest...." So if you see a fierce circuit made with npn and pnp transistors, and it is really mean and ornery, perhaps that might be because it is a Bipolar Bear.
