In S1E18, Emily is trying to find all the awful gifts her mother-in-law has given her over the years. She rants about the “lion tables and stupid naked angels with their butts!” Lorelai says, “Woah! Stupid naked angel butts? What, did David Mamet just stop by?”
David Mamot is an American playwright and screenwriter, known for “Sexual Perversity in Chicago,” “Glengarry Glen Ross,” and “The Verdict.” Mamot does have a rather distinctive style for writing dialogue, although I’m not sure “stupid naked angel butts” really fits. Lorelai could be connecting Emily’s use of language to “Sexual Perversity in Chicago,” which is full of profanity and insults.
