Late Night with Jimmy Fallon is an NBC talk show hosted by Jimmy Fallon. The third incarnation of NBC's Late Night franchise, Fallon's show debuted on March 2, 2009 after previous host Conan O'Brien left Late Night to host the The Tonight Show. The show features a variety of comedic material, celebrity interviews, and musical and stand-up comedy performances.
- March 20, 2009 - Fallon and Jason Segel talk about their love for the Muppets, and Segel's script for The Muppets. Statler & Waldorf appear in the audience to heckle Fallon and Segel.
- April 15, 2009 - Elmo appears to promote the new Sesame Street video Sesame Street: Being Green. He tells another guest, rapper Ice-T, that his rap name is "Wild Cherry". He tells another guest, video game columnist Morgan Webb, that the only video game his daddy lets him play is Pac-Man. He sings the Sesame Street theme song with the help of the house band, The Roots.
- May 22, 2009 - Jimmy showcased official entries in The Jimmy Fallon Dance Challenge submitted by Bunsen & Beaker, Animal, and Kermit. The videos (using recut footage from the Muppetism interstitials) featured a remixed version of the contest's song "The Late Night" with samplings of "Mahna Mahna". Although Fallon thanked "everyone at the Henson Company" for the videos on the air, the entries were actually produced and submitted (without solicitation) by the folks at The Muppets Studio. Of the videos, Fallon said, "that's the coolest thing ever! I love it! That's just so cool!" Show announcer Steve Higgins also commented on the videos stating that "You see the Muppets and you just feel good." Template:Hulu
- November 9, 2009 - Elmo and Rosita promote the 40th Anniversary of Sesame Street with Laurence Fishburne.

The performance is similar to the Muppets previous performance of the song from John Denver & The Muppets: A Christmas Together, but with Pepe taking the place of Janice, Sam taking the place of Statler and Waldorf, Rizzo taking the place of Floyd, and Fallon taking the place of Denver. Although, like the original, Fozzie Bear comically struggles to remember his line throughout the performance. Template:Hulu
