To have a light-hearted joke with your technical colleagues, take the highest clock rate of the fastest CPU chip on the market and quadruple it. Then, say something like "did you hear about Intel's 20 gigahertz (20 GHz) CPU? They kept it a secret for a long time but just announced it last week." Expect a "that's impossible!" reaction.
Years ago, 100 MHz (megahertz) sounded extraordinary. Today, chip speeds have 5 GHz and beyond. See also buffer flush and Stringy Floppy.
