On "Friends", what is Frank Buffay Jr.'s wife's name?

Frank Buffay Jr.’s wife on “Friends” is Alice Knight. She is introduced as Frank’s fiancée and former home-economics teacher before becoming his wife and the mother of the triplets Phoebe carries as a surrogate.

Alice is played by Debra Jo Rupp, while Frank Jr. is played by Giovanni Ribisi. Their relationship is built around an unusually large age difference: Alice is established as 26 years older than Frank. The show uses that gap for comic discomfort, especially when Frank introduces Alice to Phoebe and explains that she was once his teacher.

Alice and Frank first become central in “The One with the Hypnosis Tape.” In the following season, they ask Phoebe to be their surrogate because they want children. Phoebe gives birth to their triplets—Frank Jr., Leslie, and Chandler—in “The One Hundredth.”

Some references call Alice “Alice Knight-Buffay” after the marriage, but Alice Knight is the canonical name used when the question’s relationship is introduced. She is not Phoebe’s biological sister; she is Phoebe’s half-sister-in-law through Frank.
