Put 2 tablespoons of the oil in a skillet large enough to hold the bread in a single layer and turn heat to medium. When oil shimmers, add bread and sprinkle with salt and pepper; brown lightly on all sides, adding a little more oil if necessary. Remove and set aside. Rub the inside of a salad bowl with the garlic clove; discard it. Bring a small pot of water to a boil. Pierce a tiny hole in the broad end of each egg with a pin or needle and boil them for 60 to 90 seconds; they will just begin to firm up. Crack them into the salad bowl, being sure to scoop out the white that clings to the shell. Beat eggs with a fork. Gradually add lemon juice and 6 tablespoons oil, beating all the while. Stir in anchovies and Worcestershire. Taste and add salt if needed, and lots of pepper. Toss well with lettuce; top with Parmesan and croutons; toss again at table. Serve immediately.
