When Lawrence saw the posters for the circus hanging on the bulletin board, as he swept up the trimmings at Slim's Barbershop, h
e knew he would be taking his little cousins. They loved animals, and he was looking forward to seeing the smiles on their faces as the circus performers amazed them with their stunts. But sweeping up hair clippings didn't pay a whole lot. Lawrence spent 45 dollars just getting tickets. But it was worth it to see his cousins' faces. The day finally came and everyone was excited as they walked into that big circus tent. But Lawrence soon realized that he and his cousins would be thirsty and hungry. As they sat in their seats, the drink vendor walked by selling beverages. Desperately thirsty, Lawrence asked him how much a lemonade would cost, and the drink vendor said, "Eleven dollars each." Lawrence replied, "Oh, that's it? Just eleven dollars? What a great deal for one cup of lemonade. That's totally worth it." The drink vendor walked away. Which type of irony is used? _
When you are trying to understand irony, the very essence of it is that something happens which is unexpected. Or something happens which is the opposite of the usual, intended meaning.
This story is about some guy who wants to take his kids to the circus. We know that this guy has a bad job and just BARELY manages to get by... he doesnt get paid well...
So do you know what sarcasm is? It's when people say stuff in a mocking way, where what they say isnt what they ACTUALLY MEAN. When this guy hears about this vendor asking for ELEVEN DOLLARS for a cup of lemonade... That's kind of messed up. But notice that this isnt specifically what creates the irony.
It's what comes out of Lawrence's mouth. "Oh, really? Just eleven dollars? That's <em>totally</em> worth it!" That's not what he actually means. He's being sarcastic with his words. He's using verbal irony.
The Importance of Being Earnest" is actually a comedy play that was written by Oscar Wilde and based on the excerpt taken from this in Act II, the two meanings of the word little that the pun in this excerpt relies on are SMALL and YOUNG. Hope this answer helps.
