Some Letterman jokes connected to Carson

Do you miss Johnny Carson's comic monologues on "The Tonight Show"? So does he, apparently.

"When he reads the paper in the morning, he can think of five jokes right off the bat that he wishes he had an outlet for," said Peter Lassally, one of his former producers, who's now helping guide Craig Ferguson's career on CBS' "The Late Late Show."

Sometimes the 79-year-old Carson, who keeps up with the late-night shows from his California home, can't stand to keep them to himself.

He'll send a joke every now and then to CBS "Late Show" host David Letterman, who has used some of Carson's jokes in his monologue, Lassally said.
