How the act 1 in the importance of being earnest is dramatic or comedy?

Part of The Importance of Being Earnest's success comes from Wilde's seemingly infinite supply of piquant epigrams. Though some of the concise, often paradoxical statements refer to contemporary events (the state of 19th-century French drama, for instance), most are universal, reflections on beauty, art, men, women, and class; they are endlessly quotable and continue to delight audiences with their blend of sophistication and absurdity.
