Near the end of this episode, when Peter is looking through June's photo album, one of the photos briefly seen is of June with JFK. The actual picture is of Diahann Carroll(the actress playing June) photographed with President John F. Kennedy in 1962.
Diahannn Carroll, who plays June, and Billy Dee Williams, guest starring as Ford in this episode, were classmates at the New York City High School of Music & Art.
Early in the episode Diahann Carroll and Matt Bomer sing a lovely rendition of "One for My Baby (and One More for the Road)", accompanied by Billy Dee Williams on the piano. This is one of the songs Carroll sings on her 2010 album " The Lady, the Music, the Legend" - Diahann Carroll
