I'm sarcastic, therefore I'm brainy

According to David Robson, writing for BBC Family Tree, a teenager's sarcasm reflects their intellect. Fortunately for me, my sarcastic teen, Emily, doesn't read the BBC online.
I didn't wade through the whole article, because it's just not that interesting. But I did skip-read far enough into it, to learn that there's a codicil to Oscar Wilde's famous observation on sarcasm: Sarcasm is the lowest form of wit, but the highest form of intelligence.
Fortunately for me, Emily doesn't read Oscar Wilde either. (phew)
