I would love that to be the case, but that idiom pops up all the time in my parts (LA area).

Most recently it showed up in the dialogue for Disney's Tangled and not even in a self-aware way. Ugh.

Everything I read seems to have it that way. It makes no sense, it confuses and infuriates me.

Judging from the sibling responses, it would appear that I live a grammatically sheltered life.

I envy you.

Really? I seem to see it a lot, a regional idiom perhaps? However, the "table" example is much better.

It could be a regional idiom, like "ain't" or "y'all". I'm in the southwest, it seems like people mostly use "news english".
