For several years at my present job I was paid bupkis, with 3% cost-of-living bupkis increases every year. Then one day, my boss calls me in and tells me to 1) initial a paper saying I was getting a fat raise and, 2) shut up about it. Never one to be proud, I did as I was told.
I felt fairly chuffed about it for some time until, about a year later, the word went around that the owner of the company was announcing his retirement and that he was selling the company for a buy-out the size of the Gross Domestic Product of Monaco. Suddenly, the picture became clear: the clever s.o.b. had given everyone a raise to, as the song goes, "fatten the frog for the snake."
