In a large bowl top lettuce with celery, onion and chicken. Do not mix. In a separate bowl mix mayonnaise with vinegar and drop spoonfuls over the salad. Mix sour cream with sugar and drop spoonfuls over the salad. Spread the dropped dressings evenly over the salad with the back of a spoon to cover all of the lettuce and chicken. Sprinkle Parmesan cheese over the the dressing and grind a lot of black pepper over the cheese.
Make ahead and cover with plastic wrap. When ready to serve, add the optional bacon and toss well to evenly coat all. This is a great salad to take to an event. By not tossing it until serving, the lettuce stays crisp.
