Bad Night With Letterman

David Letterman is the prime example of the “dumbing” of America. “Late Night With David Letterman” is too late for me but I watched the “10th Anniversary Special” (NBC, Feb. 6). It was boring, not funny. His silly chuckle before and during inane events, the mindless fans ... . Luckily, I was spared his rude interviews because I gave up after Bob Dylan’s horrible act. The epitome of killing time.
