<sarcasm> Assuming you have one, of course… </sarcasm>
Seriously though - I read somewhere recently (Scientific American, IIRC) that children develop a sense of irony or sarcasm around the age of six, with (sadly common) abusive sarcasm or ironic ridicule (“oh, that was a real smart move!”) being the first to register due to the tone, and more deadpan or subtle irony the last.
The reason I suddenly thought about this today was in recalling an old jingle for Peek Freans cookies from when I was a kid. I tried looking it up on YouTube for a link but surprisingly couldn’t find one - so those of you unfamiliar with this jingle will have to take my word on the insufferable snottiness in the intonation.
I may have the lyrics a bit garbled from memory but it went kinda like this:
*Peek Freans are an extraordinarily serious cookie,
They’re made for grown-up tastes,
Peek Freans are much too good to waste on children, oh!
They’re serious, veeee-rrrry serious!
…
**Peek Freans are an extraordinarily serious cookie,
*If you’re or a grown-up, or plan to be one, you’ll know what we mean!
Peek Freans are a very serious cookie!
I was just about 6 or 7 years old when I first heard this jingle and it quite incensed me at the time. WHAT? Cookies WERE for kids! Too SERIOUS to WASTE on children? How DARE they? Who do they THINK they are? Who BUYS cookies except for KIDS? And what do they mean, PLAN to be a grown-up? What’s the alternative here? ARRGH!!
Of course the drawn out “serious… Veeerrrrry serious” was meant to be funny, and the “snottiness” was meant to be over the top enough to be “obviously” humorous, except when you’re seven years old and feel like you’re being snubbed.
It also doesn’t help that eventually I had some Peek Freans as a teenager, and found them basically on a par with Social Tea biscuits but slightly more sweet. Not bad at all, but also nothing particularly special. For this I was snubbed?
As for what made me think of it: I had cause to type the word “extraordinarily”, a word which for several years I thought was “extrordinary” (which was how I heard it in the jingle as a 7-year-old) until I was old enough and educated enough to parse the parts of speech, “extra-” meaning “beyond” and “ordinary” + “-ily” adverb ending conversion = it’s spelled “extraordinarily”. So every single time I go through that brief mental exercise to spell the word correctly, I think of the Peek Freans commercial. It drives me nuts, it does!
