Update: Oh my god look at the promo image for the episode (see below)

Monday night's episode of "Late Night With Jimmy Fallon" featured J Mascis guesting with the Roots, but that wasn't the biggest surprise of the evening. Out of the blue, at one point, Stephen Colbert ran on stage to dance to "Get Lucky" with Fallon. Turns out this was not just a random whimsical moment.

As the Huffington Post points out (via Daft Punk fansite the Daft Club), the stunt was to promote Daft Punk's upcoming appearance on "The Colbert Report". According to the Colbert fan site Colbert News Hub, Stephen revealed the big news to his studio audience during a taping on July 25. To prepare for the robots' arrival, "Stephen is doing some kind of bit where he dances to 'Get Lucky' with various guests in preparation for their appearance," Colbert News Hub reports. That day, said guest was former Senator Olympia Snowe, who got down with Stephen to "Get Lucky".

Now, it's been confirmed that Daft Punk will appear on "The Report" on Tuesday, August 6, as part of the "Colbchella" series.

So, yeah. This should be awesome.

It's not clear if Thomas Bangalter and Guy-Manuel de Homem-Christo will be interviewed or performing, or what, exactly, is going on.

Here's the promo image. This is going to be amazing:
