The grilling of the One Big Happy kids on their social / cultural knowledge as evidenced in their language use continues in the 11/30 strip (previous episode: my 12/20/20 posting “What question are you asking?”):
(#1) Note the context. One person could ask another whether they used sarcasm, just as chat or small talk, but that’s not what’s going on in the strip. This is some kind of test — note the dad’s laptop — and Joe is perfectly aware of that, though he has no idea what’s being tested.
Then there’s something of a trap in the question “Do you use sarcasm?” It’s perfectly possible to know how to use sarcasm without knowing that the contemptuous verbal practice you’re engaging in is in fact called sarcasm: you know how, but you don’t know what it’s called. As turns out to be the case for Joe: he can wield sarcasm just fine — he uses a sarcasm-devoted linguistic form in Like I know what X is, conveying that you don’t know what X is and expressing contempt for someone who expects that you should.
