"Alexis Goodlooking and the Case of the Missing Whisky" is the tenth episode of the sixth season of the American television comedy series 30 Rock, and the 113th overall episode of the series. It was directed by Michael Slovis, and written by John Riggi. The episode originally aired on the National Broadcasting Company (NBC) network in the United States on March 1, 2012.

In the episode, Liz (Tina Fey) helps Frank (Judah Friedlander) hide his relationship with Lynn (Susan Sarandon) from his mother (Patti LuPone) by pretending to be his girlfriend; Jack (Alec Baldwin) advises Kenneth (Jack McBrayer) to destroy a potential rival in his new job; and Jenna (Jane Krakowski) uses skills from an old role to solve the mystery of who took Pete's (Scott Adsit) whisky.

Frank's mother Silvia (Patti LuPone) confronts Liz (Tina Fey) in the writers' room for allegedly having an affair with Frank (Judah Friedlander), before realizing that she approves of the match. After she leaves, Frank admits that he lied about their relationship to cover up his longtime affair with his old middle school teacher, Lynn Onkman (Susan Sarandon). When he excuses Liz from dinner with Silvia by saying she is sick, Silvia shows up at Liz's apartment with Frank and a home-cooked Italian meal. Liz goes along with the charade for the food, until Frank confesses to his mother and breaks up with Lynn. Although he claims to be fine, Liz realizes Frank is suffering and orchestrates a reunion with Frank and both women where Silvia accepts that Lynn and Frank love each other.
