Recently I wrote about the term "Jibber Jabber" and its re-emergence in Toobworld.
A week or so later, and it showed up in the season finale of 'Lost'. After the trek through the woods to reach the Others broke down into a pointless discussion, Sawyer griped that there had been "Enough jibber jabber".
I don't see it as an 'A-Team' Zonk! however. More than likely, it's just a phrase that gets a lot of play in various regions of TV Land.
That the judge in 'Boston Legal' uses it all the time, maybe he got it from B.A. Baracus, after the 'A-Team' member appeared before him in court there in Beantown.
