No matter what talents (not many) he displayed on the floor on "Dancing With the Stars," and no matter how well he runs a professional basketball operation, [tag]Mark Cuban[/tag] can butcher the English language with the best of us.

Here’s a NotPhrase he used on TV tonight and one I sometimes use myself:  "A whole ‘nother thing."

I’m not sure how one would correct that.  "A whole other thing altogether" would seem to be the most logical and correct usage.  Or use "a different matter altogether"–there you go!

I wouldn’t be surprised if the folks at the Oxford dictionary haven’t already added ‘nother, but they probably spelled it nother.
