Regardless, it is an annoying thing to say (as are most idioms). They come out of our mouths like an idiomatic tourettes syndrome. When Googling the "hey is for horses" line, I found thread after thread of people fixating on the stupid idioms they learned from their parents. And I cringe because I say some of these things:
See ya, wouldn't want to be ya.
Well...deep subject for such a shallow mind.
Hello...hell's low and heaven's high.
(when someone trips) Have a nice trip, see you next fall.
(when someone asks if I got a haircut) More than one.I am so ashamed. I don't want to say these things but they are so ingrained into my involuntary speech monitor that I can't seem to reel them in. I do have to say that I found a few funny ones to add to my arsenal while doing my search:
(when someone says they are going to the bathroom) Mention my name and they'll give you a good seat.
(when someone say they "wish" something would happen) Put your wish in one hand and take a dump in the other and see which one gets filled sooner.Oh my god. Please don't let me start saying those things, too. Damn you Google!
