Strunk White, Idiot Weatherman: Mirror Images

Strunk White, Idiot Weatherman, forecast the precipitation probabilities for the past 3 days (including today) thusly: 100%, 80%, and 0%. It didn't rain a drop the first 2 days (the sun was even out yesterday). Today, as I look out the window, it is pouring rain with no end in sight. Strunk White, Idiot Weatherman, can come cut my foot-high grass for me, since I put it off until today due to the surety of rain on the previous two.
