It's holiday time and the staff of TGS is having their annual "Ludachristmas" party.

Jack (Alec Baldwin) assumes a new political role in Washington, DC. When the job is not what he expected, Jack partners with another government employee, Cooter (guest star Matthew Broderick), to scheme on how to get fired. For his plan to work Jack must enlist the help of former girlfriend C.C. (guest star Edie Falco). Meanwhile, Liz (Tina Fey) is slowly adjusting to life without Jack as a daily sounding board especially when she has a pregnancy scare involving Dennis, the former Subway Hero (guest star Dean Winters). Kenneth (Jack McBrayer) is preparing his personal essay for an application to be a page at the Summer Olympics in Beijing, but Donny, the head page (guest star Paul Scheer) gets in his way. Finally, Tracy (Tracy Morgan) is in the advanced stages of the invention that will be his legacy to his children. Matthew Broderick, Edie Falco, Dean Winters, and Paul Scheer guest star. Also stars Jane Krakowski, Scott Adsit, Katrina Bowden and Maulik Pancholy.

Liz falls for an attractive guy and Jack walks in Kenneth's shoes --- Intrigued by two MSNBC guys - the cerebral nerd "The Head" and the gorgeous hunk "The Hair" - they keep running into inside 30 Rock, Liz and Jenna decide to get serious about their dating lives, but find themselves unexpectedly switching their typical roles when Liz admits she's clicking with - and falling for - The Hair. Jack and Kenneth the Page also switch office roles for "Bottoms Up" day, with Jack donning the page jacket and Kenneth spending a day as a corporate big wig.

An angry Jerry Seinfeld goes to 30 Rock to confront Jack after he learns that Jack plans to digitally insert him into every current NBC program. Meanwhile, Liz buys a wedding dress, even though her marriage prospects are slim.

In an effort to cut off any chance of GE digging up dirt against him, Jack hires his own private investigator to head them off.
