Tony: (to Gibbs, after Ray's proposal to Ziva) Hey, you should be getting ready to play Father of the Bride. I'd base it on the Spencer Tracy classic -- skip the Steve Martin.
Gibbs: Yeah? I'm happy for you, Ziva.
Tony is referring to Father of the Bride (1950), a movie starring Spencer Tracy dealing with the trials of preparing for a wedding as a father of a bride, played by Elizabeth Taylor. The movie was remade in 1991, starring Steve Martin in the Spencer Tracy role.
