Two pet peeves come to mind immediately:

Using a sentence with the constructions "neither-or" rather than "either-or" or "neither-nor". I will, though, say that I can't remember either seeing nor hearing "either-nor". That would probably be the very last words I heard before the fatal stroke.

Using I, she, he, etc. in prepositional phrases where me, her, or him is correct. I have been known to call newscasters and "caster"gate them for this unforgiveable lapse.
