I've been noticing people using the construction "The thing/problem is is" quite a bit lately("The thing is is that I don't want to do that", for example, or "the problem is is that nobody wants to be seen being nice to a jerk).  Often there is a pause after the first "is".  It seems to me that "the thing/problem is" is being treated by the speaker almost as  a compound word that indicates complication or objection, with the "is" in it not functioning as a verb in the sentence.
So for Jon and goofy, do you guys agree that that's what's happening here?  Is there a name for it?  Are there other phrases in English that are going this direction?  And have I brought this up before?  I'm getting a feeling of deja vu.
