The Importance of Being Earnest (Algernon)

Algernon says

Why does your aunt call you her uncle? ‘From little Cecily, with her fondest love to her dear Uncle Jack.’ There is no objection, I admit, to an aunt being a small aunt, but why an aunt, no matter what her size may be, should call her own nephew her uncle, I can’t quite make out. Besides, your name isn’t Jack at all; it is Ernest. You have always told me it was Ernest. I have introduced you to everyone as Ernest. You answer to the nameof Ernest. You look as if your name was Ernest. You are the most earnest-looking person I ever saw in my life. It is perfectly absurd your saying that your name isn’t Ernest. It’s on your cards. Here is one of them. I’ll keep this as a proof that your name is Ernest if ever you attempt to deny it to me, or to Gwendolen, or to any one else.
