A late night TV host’s legacy isn’t only about crafting a skillful monologue, executing ingenious comedy bits, and possessing an easy manner with one’s guests and the audience: it’s about moving the fence posts back and creating more space for comedy to live. To some, the audience can seem expansive and almost limitless, but you can’t reach everyone and some people have ever-shifting rules about what they think is an acceptable topic or joke.
Johnny Carson conspired against those rules and those fences when he took over The Tonight Show, creating more space for his comedy and future late night hosts, while giving them more freedom to be funny in their own way.
People’s minds don’t get more open on their own, they have to be gently nudged and that’s what Carson did with his comedy. He moved the fence posts every time he got away with a bit, some innuendo, or a knowing look. Carson did this for a long time, but eventually, one retires from the subtle rebellion against society’s bland proclivities and they sit and they wait for the next person to take the baton…
Sometimes, one does more than merely sit and wait.
As the story goes, Carson’s hunger for leisure inadvertently led to the birth of Saturday Night Live, but he also helped establish David Letterman as the next great undercover troublemaker with the creation of Late Night. Carson’s production company co-produced the show and instituted guidelines that would ensure minimal tonal overlap.
Since Late Night followed The Tonight Show, Letterman couldn’t have a sidekick like Ed McMahon, and Paul Shaffer’s band couldn’t include a horn section like Doc Severinsen’s. What’s more, Letterman was told he couldn’t book any of the old-school showbiz guests – the Don Rickles and Bob Newharts of the world – who were fixtures on Johnny’s couch. To make sure the restrictions were obeyed, a Carson representative visited the set several times a week. “The Carson show also asked us very specifically not to replicate any of their signature pieces,” Markoe recalls. “I remember thinking, ‘So if we can’t do “Stump the Band” or the “Great Carsoni” – what, oh what, is left for us to do?'”
Though I can’t be sure, I think it’s safe to assume that these rules weren’t put into place solely because Carson sensed a kindred spirit who needed someone to set a pick for him with the network so that he could carry the baton and do his weird little show and push back his share of fence posts. It was simply in the best interests of Carson’s show to not have a similar program with a cheaper and younger host on NBC.
If anything, Carson probably never imagined how far outside of the box Letterman would go to entertain his audience (and himself) and he probably underestimated the public’s appetite for an alternative and less predictable late night show. In doing that, and in blessing NBC’s decision to go with Letterman to replace Tom Snyder at 12:30, Carson had a slight hand in illuminating the time-worn flaws in his own show over that last decade, but that’s the circle of life and it always seemed like Carson respected Letterman, perhaps because he carved out his own path and didn’t ride in on his coattails. That respect was evident in Letterman’s appearance on Carson’s show after losing The Tonight Show, Carson’s decision to appear on The Late Show after he retired, and the fact that Carson would send along monologue jokes to Letterman for years after he left the air.
