What? I didn't say anything outright wrong, though it's a subject of some controversy. See here: http://en.wikipedia.org/wiki/Irony#Verbal_irony_and_sarcasm

More specifically: Some psycholinguistic theorists (e.g., Gibbs, 2000) suggest that sarcasm ("Great idea!", "I hear they do fine work."), hyperbole ("That's the best idea I have heard in years!"), understatement ("Sure, what the hell, it's only cancer..."), rhetorical questions ("What, does your spirit have cancer?"), double entendre ("I'll bet if you do that, you'll be communing with spirits in no time...") and jocularity ("Get them to fix your bad back while you're at it.") should all be considered forms of verbal irony.
