Toward the end of the episode, when Tom and Julia decide to live together, he mentions that it could be like a sitcom. This may be a subtle nod to the show Will & Grace, in which Debra Messing, who plays Julia, starred (and now stars again) where she lived with her gay best friend.
Though they share no scenes here, Wesley Taylor (Bobby) and Krysta Rodriguez (Ana) previously starred together in the Broadway production of The Addams Family Musical as love interests. Interestingly, Anjelica Huston (Eileen) was the lead actress in The Addams Family (1991) and Addams Family Values (1993).
[February 2013] Krysta Rodriguez (Ana) and Andy Mientes (Kyle) are both currently in Deaf West's Spring Awakening on Broadway.
