It has to be one heck of a sight to see, being able to be an audience member and watch David Letterman interview Conan O’Brien. They’re easily both kings of late night talk shows and have been adored by the masses for years. Now they’re meeting up once more, making plenty of late night talk show fans very happy.

It was announced today that Conan O’Brien would be making a return appearance to ‘The Late Show with David Letterman.’ This is the first time that Conan O’Brien will be popping his head on Letterman show in thirteen years. Talk about a long time.

Conan will come onto the show this May 17th, which is great for television fans because that means they don’t have to wait too long for this to happen. Conan isn’t the only guest who will be appearing on this episode: the other special guests scheduled include Regina Spektor and musician John Mayer (during the show Mayer will be performing alongside Paul Shaffer and the band).

What makes this sudden appearance really cool? It’s the fact that these two are practically late night legends. The fact that they’ll be sitting next to each other talking about anything and everything (likely their mutual dislike for Jay Leno) is enough to get anybody excited for this episode. ‘The Late Show with David Letterman’ airs on CBS at 11:35/10:35 PM Central.

You can watch the last time Conan was a guest on ‘The Late Show’ back in the late-90s below.
