The best method I've found to peeling the shell off without destroying the egg is to find the air bubble and start peeling there. You should be able to see the gap between the egg white and the shell. If you can't find an air bubble, gently tap the pointy edge of the egg with the back of a spoon (not on the counter) and begin carefully peeling. You can also try adding a touch of vinegar and salt to the boiling water to help the shell to come off a bit easier.
