I missed the David Letterman, show last night (3/16/10) to catch Betty White on Leno. Checking the web this morning, I read the buzz about Jimmy Kimmel's appearance on Letterman's show. Jimmy Kimmel of "Jimmy Kimmel Live!", the late-night talk show that airs on ABC, and David Letterman of CBS late night show -- What did Kimmel and Letterman talk about? NBC's Jay Leno. What else? Letterman and Kimmel swapped stories about one of their favorite targets / topics, Jay Leno. I caught a clip of the Letterman and Kimmel exchange -- Yes, some of the jokes were funny, but that is not the point. It is not a good sign when the two of them feel the need to team up to trash Leno. After one week back at the 'Tonight " show desk, Leno has placed the NBC show back on top. Letterman must be feeling the heat. Stay tune. Somehow, I feel that a Leno response is coming.
