Hello. As you might have guessed by my username, I am John. (pauses for applause). I have decided to make a blog on the subject of sarcasm. Why would I make a blog about sarcasm, you may ask? Well, dear reader, sarcasm is, in my opinion, an art. A great art. One must use sarcasm skillfully and with intelligence. One does not simply spew a random comment and deem it sarcastic. Well, what is sarcasm, then? Well, it looks as if you must follow this blog and become a pupil of mine in order to learn of the great wonders and mysteries of the art of sarcasm.
