(PEOPLE.com) — Late-night TV can usually be counted on for a steady diet of jokes. Now it is the joke.

David Letterman joined in the skirmish Tuesday by making jokes about NBC’s late-night host shuffle on the “Late Show,” according to a transcript of his opening monologue.

NBC vowed Sunday to push Conan O’Brien and the “Tonight Show” back to 12:05 a.m. to make room for “The Jay Leno Show” at 11:35 p.m.

O’Brien balked at the idea, saying he refused to take part in the “destruction” of the “Tonight Show” brand and blasted the network for trying to patch up its ratings problems in prime-time by toying with its late-night lineup.
