Late Night Highlights: Tina Fey Blacks Out on Emmy Night, Leno Solves the I'm Still Here Mystery

Fall premiere week is exciting for everyone, especially late night audiences who get to see their favorite primetime stars pass through the P.M. talk shows. Last night alone, Tina Fey told Jimmy Fallon about how she blacked out with Jon Hamm at this year's Emmy parties, Modern Family's cast discussed getting into bed with George Clooney, Snooki taught David Letterman how to fist pump, Ed Helms premiered a new Office dance sequence... and completely unrelated to television, Jay Leno got to the bottom of the I'm Still Here controversy.

5. Dave Fist Pumps

When Jersey Shore starlet Snooki stopped by The Late Show, she taught David Letterman about everything from fist-pumping to smooshing. Poor Dave.

4. Ed Helms, Office Rock Star

Ed Helms premiered a new song and dance sequence from The Office on last night's Tonight Show before telling Jay about the time his parents visited set and he got all "cagey" with the cast and crew.

3. Jay Leno Investigates the I'm Still Here Confusion

Add this to your growing "Jay Leno Is Just Like Us!" case: The Tonight Show host was unsure whether Joaquin Phoenix's cranky Letterman interview and Casey Affleck-helmed documentary was real. Leno investigated when Affleck stopped by the show.

2. George Clooney Visits Modern Family

Modern Family stars Julie Bowen, Ty Burrell, Jesse Tyler Ferguson and Eric Stonestreet stopped by Jimmy Kimmel Live! to talk about shooting their Emmy scene with George Clooney and Bowen's beer pong-playing babysitters.

1. The Night of the Drunk TV Moms

It may seem like a fun idea to try to keep up, alcohol-wise, with Jon Hamm at an Emmys after party, but it is not -- at least according to Tina Fey who last night told Jimmy Fallon all about her blackout Emmys night.
