“How many of you folks earlier today saw the white smoke coming out of the chimney at NBC? Anybody see that?” David Letterman — the guy who Leno did out of “Tonight Show” back when Carson retired — said at the top of his CBS late night show hours after NBC’s announcement.

“I got a call from my mom today, she says, ‘Well, David, I see you didn’t get the ‘Tonight Show’ again,’” Letterman continued.

“Good luck to Jay. I know he’ll be out on the road, getting it done and taking care of business and congratulations on a nice long run there at the ‘Tonight Show,’ if in fact you’re not coming back.”

And, Dave’s Wednesday Top 10 List?

Things We’ll Miss About Jay Leno, including:

5. If you broke down on the freeway, Jay was always right there with a camera crew to help.

4. Can’t remember the name of the bit, but it’s the one where Jay is walking.

3. He’s mom’s favorite talk show host.

And so on.
