1Place bacon in a large, deep skillet. Cook over medium high heat until evenly brown. Drain, crumble and set aside. Bring a large pot of lightly salted water to a boil. Add the macaroni pasta, and cook until al dente, 8 to 10 minutes. Drain and rinse with cold water.
2Whisk the mayonnaise, sour cream, mustard, sugar, vinegar, salt, and pepper in a large bowl until the sugar has dissolved. Add the bacon, pasta, tomato, cucumber, egg, and celery. Gently fold until the salad is evenly covered with the dressing. Sprinkle with the sliced olives to serve.
