I seem to remember an American exam paper said there are six types of irony in Pride and Predjudice, and the poor sods had to try and work out them all.

I wonder how we read the book without appreciation and failing to spot all that irony.

I had to teach His Last Duchess, a poem by Robert Browning. I was discussing it with a friend and he gave me this great definition of irony.

Irony is when you say something, but mean something else.

Now what the something else might be in this case....?
maybe he or she is saying our singer song writers are shit and we have nothing to be proud of.
