One of the possible upshots to the Conan-taking-over-The-Tonight-Show scenario is that it could have freed Jay Leno to do many things elsewhere, away from NBC. In fact, he could have gone on The Late Show with David Letterman the night that Conan takes over his NBC show and be Dave's guest for the first time in...well, a very, very long time. But now that seems like it's not going to happen.

Leno reveals to The New York Times that The Late Show really did invite him to be the guest on the show that night, but Leno says that he doesn't want to do that to Conan. And I have to agree with him on this. It would be kind of a kick in the teeth to have Leno guest on Letterman's show at the same time Conan is launching his hosting duties on The Tonight Show. Leno shaking hands with Letterman again and sitting in the chair will be must-see television for everyone who watches late night, so you know that Conan would be hurt by that (ratings-wise and probably personally too).

Leno does, however, hope to do Letterman's show at some point. Even though he's still with NBC, he'll be on at 10pm now and won't be competing with Dave anymore.
