When David Letterman came on the scene in the early 80’s everyone knew he had a sharp wit. Everyone also knew that he wore sneakers with a sport jacket and took almost nothing seriously. Fast forward to 2012. David Letterman still flashes his toothy smile and is often irreverent but he’s decidedly matured. This Bill O’Reilly interview never would have happened 30 years ago with a political discussion more suited for his former late night rival Tom Snyder. Dave is still funny though and uses humor to disarm a loud mouthed O’Reilly. Then follows it up with cutting political observations that seem far too intelligent for a late night comic to be making as he lampoons all that is FOX, Rush Limbaugh and Bill O’Reilly.
