Try holding up a stopwatch, set to 3 minutes, and a loaded gun, aimed at the ostrich. Look at the ostrich meaningfully as the seconds tick away toward zero. I predict the ostrich will produce the egg on time in 9 out of 10 cases. In the 10th case you fire the gun, makin' sure to just barely miss the ostrich, and the ostrich WILL produce an egg on the spot. This method has never failed for me.
