Saying 'That's easy' after someone succeeds is like the egg of Columbus.
Etymology From the anecdote about Christopher Columbus, who, after being told his discovery of the New World was no great feat, challenged critics to stand an egg on its tip. When they failed, he cracked the egg slightly and stood it up, demonstrating that the simplest solution seems obvious only in hindsight.
