The Importance of Being Earnest - Oscar Wilde
I always thought Who's Ernest? Whenever this play's name came up, and learned only (much) later that it was the characteristic, not a person's name, that this, one of the most popular of Wilde's plays, was based on. All very confusing to someone who was (is), easily confused, but the fact remains that this is one of the All-Stars of Wilde's prolific accomplishments. Like new copy.
