In 20 Hours in L.A. (2000) at the LA party, Donna walks away from Josh to go stalk Matthew Perry. Matthew Perry appears as Joe Quincy and Donna comments on him being considered cute by most staff. He will also appear in Sorkin's next TV show "Studio 60 on the Sunset Strip".
When C.J. responds to Toby's question, "Faith?", she quotes the Bible, Hebrews 11:1. This episode's title is also taken from this verse.
This episode makes multiple references to the Jewish Passover. Among them is the emphasis on eggs throughout the episode. Eggs are commonly served during the Seder. In one scene CJ refers to gefilte fish and blessing the soup. Gefilte fish and matzah ball soup are also typical elements of the Passover feast. Toby responds to her references by saying, "Suzy Cream Cheese, do not attempt the Haggadah." The Haggadah is a Jewish text that sets forth the order of the Passover Seder. During Charlie's conversation with Zoey she challenges his remarks by asking why he would say those things "tonight of all nights." Charlie's response, "Why is tonight different from other nights?" Is a paraphrase of one of the four questions asked during the Seder. The original air date for this episode, April 23, 2003, fell during the Passover that year. Even the title of the episode, which is reflected in one of CJ's lines during the episode, is a quote from the New Testament book of Hebrews, which was written to Jews in the early days of the Christian church.
