God, what an asshole. I mean, say those out loud! Incorrect actually demonstrates this really well -- "You're probably using it wrong." versus "You're probably using it incorrect." -- because then you see that wrong can really, really quite obviously be used as an adverb, too, and incorrect can't be.

Hell, my syntax professor actually believes there's no such thing as a adverb/adjective distinction.

Ah, I misunderstood who was talking. WHATEVER GUY'S STILL A DICK.

Aha, I use well and good totally wrong when I speak casually. I also conjugate lots of verbs wrong and use ain't pretty liberally, so this is probably not surprising.
