Amy Poehler Cosmo Cover

Jimmy digs up a cover of "Cosmopolitan" from 1934 with a very familiar looking woman on the front, and the two talk about Amy's show, "Parks and Recreation."

Late Night with Jimmy Fallon.

Jimmy Fallon, Mariah Carey, & The Roots

Backstage before the show, Jimmy, Mariah Carey, and The Roots grabbed some instruments you'd find in an elementary school classroom and stopped by the Late Night "Music Room" to sing Mariah's holiday classic, "All I Want For Christmas Is You."

SNL: The Barry Gibb Talk Show, 2003

Justin Timberlake hosted and performed as the musical guest on the premiere episode of The Barry Gibb Talk Show.

Barry's guests included Al Franken (played by Jeff Richards), Arianna Huffington (Rachel Dratch) and the then-Lieutenant Governor of California, Cruz Bustamante (Horatio Sanz). At the time, both Huffington and Bustamante were running for Governor of California amidst the recall election that eventually ousted Gray Davis.

The show is memorable for Timberlake's inability to maintain a straight face during Fallon's rantings. He can be seen lowering his head occasionally in an attempt to disguise his laughter. This was the only Barry Gibb Talk Show sketch in which Fallon was still in the cast.
