After finding out that Carter may have family money, Malik digs out a copy of Chicago Magazine, featuring the 50 richest people in Chicago. According to that magazine, Carter's father is named Roland, but in subsequent episodes he is named John 'Jack' Carter.
This episode indicates that Carter's dad is the one with all the money, but later it's found that Carter's grandparents are the ones with all the money.
Jerry: (about two patients) Do they have names?
Haleh: Yeah—dumb and dumber.
Benton: Must be nice not having to worry about loans, huh, Carter?
Greene: Is Carter loaded?
(while examining fifteen Catholic high school girls for meningitis)
Carol: Examining all these girls in one day must be a fantasy come true.
Ross: (laughing) Fifteen years too late.
(Howard Davis, for whom the Davis Cardiac Wing is named, comes to the ER with a cut on his hand from slicing a bagel)
Jerry: I hope it wasn't the hand he writes the checks with.
Jerry: I joined a Shakespearean theatre group. I'm going to play Romeo.
Lydia: Comic version?
Title: "Love Among the Ruins"
There are many different sources the episode title could be alluding to: a Robert Browning poem from 1855, a 1904 Warwick Deeping novel, a 1948 Angela Thirkell novel, a 1953 novella by Evelyn Waugh, to name a few. But probably the one which could be associated most with this episode is the 1975 made-for-TV movie with the same title, starring Katharine Hepburn and Laurence Olivier, about an aging actress who hires an ex-lover as her lawyer. He is still in love with her, although she doesn't know it.
Jerry: Ah, what a glorious morn. "Night's candles are burnt out, and jocund day stands tiptoe on the misty mountain tops."
This is dialogue from Act III, Scene V, of William Shakespeare's Romeo and Juliet, where Romeo replies to Juliet's query as to whether he has to leave and her statement that it is not yet day:
"It was the lark, the herald of the morn,
No nightingale: look, love, what envious streaks
Do lace the severing clouds in yonder east:
Night's candles are burnt out, and jocund day
Stands tiptoe on the misty mountain tops.
I must be gone and live, or stay and die."
