I usually do over easy eggs 2 at a time in an 8 inch skillet with a dab of butter. Rather then flip with a spatula, I do the chef thing of tossing them over. Wait until the whites are reasonably well set, not moving the eggs around. Then jiggle the pan to make sure they aren't sticking anywhere. (If they are, use a rubber spatula to loosen them) Tilt the pan to get the eggs to slide to the far edge and give the pan a short, upward and backward jerk. You have to get brave with it, timid will result in a mess.
I've been doing it for years, at first I broke a lot of yolks. But I kept practicing and now I can do it in a cast iron skillet over a fire. The 8 inch skillet with sloping sides really helps to get it right at first. That and be bold, don't hesitate!
Actually, as they get older the white gets thinner and runnier. It spreads out all over instead of staying compact and pretty.
