"One of my main goals is to make the Blow Job Principle as popular as, say, Murphy's Law. That is, someday I hope that someone will go into the office of the CEO of a major company or nation and say, "You goddam idiot! Don't you even understand that the Blow Job Principle applies here? If a person expects to get a second blow job, the recipient should make the giver glad to have performed the first." And the CEO will say, "You're right. You did a good job on that project, and I neglected to show my appreciation." Then he'll give the other person a blow job; but since the Blow Job Principle is actually a metaphor, the CEO will simply give the other person a raise or public praise or something like that."

In other words, if you praise someone for giving you a blow job, you're more likely to receive a second one from them.
