Fry bacon in a medium-sized skillet over medium-high heat until crisp. Remove bacon pieces, set aside.
Reduce heat to low. Add butter. Slowly heat to warm.
In a separate bowl, combine eggs, vinegar, sugar, salt and pepper. Add a little at a time, stirring constantly into the butter cream mixture. Increase heat and cook until thickened.
Add cooked bacon, stir. Pour over greens and serve immediately.
