Right after President Bartlet reels off a list of Bible quotes to Jenna Jacobs to illustrate their inapplicability, Sam Seabourn takes a crab puff from her. This is not an isolated gesture of stealing food; Leviticus 11:10 indicates that shellfish are an "abomination", so Sam's action in effect continues the President's argument. Also, Jacobs is wearing a brooch shaped like a crab on her lapel.
President Bartlet criticizes a religious fundamentalist radio talk show host named Jenna Jacobs with his detailed knowledge of scripture. The segment was adapted from a famous Internet chain letter allegedly sent to Dr. Laura Schlessinger, on whom the Jacobs character was based, and several of Bartlet's questions are identical to the questions posed in the letter.

At the dinner party CJ (Allison Janney) mentions shock jock Howard Stern. Allison Janney played DeeDee, Howard Stern's former boss at WWDC in the movie Private Parts (1997).
