Also, in 1993, on the first broadcast of "Late Show with David Letterman" on CBS, in response to David Letterman's monologue containing jokes about NBC, Brokaw walked on stage in a surprise cameo (accompanied by Paul Shaffer and the CBS Orchestra playing the "NBC Nightly News" theme). He congratulated Letterman on his new show and wished him well, but also stated he was disappointed and shocked; he subsequently walked over to the man holding the cue cards, took two, and remarked, "These last two jokes are the intellectual property of NBC!", leaving the stage afterwards. Letterman then remarked, "Who would have thought you would ever hear the words 'intellectual property' and 'NBC' in the same sentence?"
