LORELAI: I swear, there is nothing in the world my mother is better at than getting someone to agree to something that in any other universe, they would never ever consider … I am still convinced she had something to do with Lily Tomlin doing that movie with John Travolta.
Lorelai is referring to the 1978 romantic drama Moment by Moment, directed by Jane Wagner. It stars Lily Tomlin as a wealthy middle-aged Beverly Hills socialite, and John Travolta as a young drifter. He becomes infatuated with her, and they embark on a rocky May-December romance. The film was widely panned by both critics and audiences. It remains a camp classic to this day – exactly the sort of film Lorelai couldn’t resist watching.
