As the long holiday weekend comes to an end, catching up with a humorous,
seemingly spontaneous, moment on the last fresh Late Show before
Thanksgiving. David Letterman is a big believer in cataclysmic
predictions about global warming, but on Wednesday's program his mom,
Dorothy, rejected his proposition that global warming was to blame for
some unseasonably warm days in Indianapolis - prompting her
disappointed son to shake his head in disapproval. (Audio clip )
Dorothy, better known as "Dave's mom," appears annually from her kitchen in suburban Indianapolis to let her son guess the types of pies she's baked  for Thanksgiving. This year, the 89-year-old remarked "it's been unseasonably warm," leading her son to assert "that's that climate change. It's the global warming. You know that, mom? Do you believe in the climate change, in the global warming?"
To which, Dorothy Letterman innocently responded: "Not really."

DAVID LETTERMAN: How are things in Indianapolis?
DOROTHY LETTERMAN: Things are very nice. It's been unseasonably warm.
DAVID LETTERMAN: How warm. How warm has it been? Like 20 degrees warmer than it should be?
DOROTHY LETTERMAN: About, yes, and it's very windy.
DAVID LETTERMAN: Yeah, well, that's that climate change. It's the global warming. You know that, mom? Do you believe in the climate change, in the global warming?
DOROTHY LETTERMAN: Not really. [audience laughter as David Letterman's facial expressions show his disapproval]
