Mamma Mia (30 Rock)

Jack Donaghy (Alec Baldwin) decides not to search for his biological father, after it was revealed in the previous episode that the man he believed was his father was not. Liz Lemon (Tina Fey), however, convinces him to find out who his real father is, so Jack contacts Lenny Wosniak (Steve Buscemi)—a private investigator—to search for his biological father. Lenny gives him an envelope containing the names of three individuals who could be his father. Jack tells Liz about the envelope, and she suggests they Mamma Mia! this and bring the three men to New York under false pretenses, to which Jack agrees. Jack meets the men, George Park, Fred O'Dwyer (Stuart Margolin), and Professor Milton Greene (Alan Alda). At meeting the three men, Jack comes to the realization that Milton is his father, as George Park is Korean and Fred O'Dwyer lost his genitals in a grenade explosion during World War II. He tells Milton that he is his son, after Milton admitted to sleeping with his mother, Colleen Donaghy (Elaine Stritch), around the time Jack was conceived. Milton is happy to have him as his son, and reveals to Jack that he is in need of a kidney transplant.

Meanwhile, Tracy Jordan (Tracy Morgan) introduces his illegitimate son, Donald (Michael Benjamin Washington), to the TGS with Tracy Jordan staff. Liz and Pete Hornberger (Scott Adsit) suspect that Donald is embezzling from Tracy as they do not believe that Donald is twenty-one years old, which Donald claims to be. Cerie Xerox (Katrina Bowden), Liz's assistant, obtains Donald's birth certificate and gives it to Liz and Pete; the two learn that Donald is forty years of age, thus confirming their suspicions about him. Liz tells Tracy about this, but Tracy knew all about Donald's scam, explaining he decided to go along with it because Donald was putting all of the money into a dojo and doing good for the community.

At the same time, Liz becomes jealous when her friend and TGS star Jenna Maroney (Jane Krakowski) takes credit for "That's A Deal Breaker, ladies!" catchphrase, resulting in Liz not getting recognition as she wrote the sketch. As a result of this, Jenna is named the "Funniest Person in New York" by Time Out magazine, and seeing how Liz feels about this, Jenna decides to share the magazine cover with her. At the photo shoot, the photographer (Clayton Dean Smith) wants Jenna to use props for the shoot, but Jenna is reluctant to use any of them. Liz, however, decides to pose with the props, resulting in her being on the cover of Time Out, much to Jenna's displeasure.
