The entire special itself pays tribute to every one of NBC television themes from late-night to daytime programming, radio days, early entertainment, comedy, drama, sitcoms, specials, movies, sports, and news, just to name a few. In the end, Malcolm and Keshia meet up with Johnny Carson himself on a stage full of NBC's guest stars singing a closing version of the opening theme, "Hey Did You Know?" As the camera pans outward to reveal all the stars on screen, a new version of the NBC peacock logo is unveiled, this time with six feathers. This marks the debut of the "current" NBC logo (as well as the NBC Productions logo with the current logo).
