It’s holiday time and the staff of "TGS with Tracy Jordan" is having their annual "Ludachristmas" party -- complete with music, merriment, "The Human Table" and a Horny Santa. Unfortunately, Tracy (Tracy Morgan) can’t participate due to his newly court mandated alcohol monitoring bracelet. Since holidays mean special family time, Liz’s (Tina Fey) parents, Dick (Guest star Buck Henry) and Margaret (Guest star Anita Gillette) Lemon, and her 40-year-old brother Mitch (Guest star Andy Richter), who suffers from memory loss due to a skiing accident and thinks he is a 17-year-old high school senior, come to gloat over their "beautiful genius" daughter. Jack’s (Alec Baldwin) jaded mother, Colleen (Guest star Elaine Stritch), even shows up unexpectedly from Florida. The Lemons and the Donaghys go to dinner together, where Colleen spends the night trying to break the eternal optimism of the Lemon family. Meanwhile, in the spirit of Christmas cheer, Kenneth (Jack McBrayer) decides to teach the writing staff a lesson on gratitude by inviting a priest to the party. Also stars Jane Krakowski, Lonny Ross, Judah Friedlander, Scott Adsit, Katrina Bowden, and Maulik Pancholy. Special guest stars include Elaine Stritch, Andy Richter, Buck Henry and Anita Gillette.
