Professor Smith: I'd really like a raise. Jones over at Enormous State University makes 50% more than me, and I kick his ass scientifically.
Dean: So you say. Prove it!
Smith starts writing job applications. He gets a set of interviews, and then eventually a big offer from Ivy-covered College. He shows the letter containing the big offer to the Dean.
Dean: I notice we're underpaying you here, Smith. We'll rectify this immediately!
Board of Regents: How about a free house? And maybe a pay raise?
Administrator: Oh, OK!
