"unless and until"

Is this not the most useless and obnoxious phrase...or at least at the top of the list?

I first heard it used by Dr. Phil in one of his tough ultimatums. (Never mind why I was watching Dr. Phil...though this may have been the last straw because I haven't watched it since.) I don't know if it's increased in popularity due to his pseudo psycho clout or if I'm just hypersensitive to it now, but it seems to be cropping up more and more and it really grates on my nerves. Technically, "unless" and "until" are two different concepts, but one or the other is totally &^%(*#@ unnecessary.

There. I got it off my chest. I wouldn't feel better unless or until I accomplished that. (It hurts!)
