- "Day In-Day Out" by Robert Davi
- Aaron Hotchner: A Chinese proverb says, "At the gambling table, there are no fathers and sons."
- David Rossi: George Augustus Sala said, "A gambler with a system must be, to a greater or lesser extent, insane."
- The term "snake eyes" refers to a possible outcome of rolling a pair of dice, in which one pip for each dice is received. The term was coined because the pair of pips resembles the eyes of a snake, which in turn has a longstanding association with betrayal and treachery. Because it is the lowest possible roll, which easily results in a loss in many dice games, the term has been associated with bad luck.
- Robert Davi, who performed the song "Day In-Day Out", previously portrayed Detective Adam Kurzbard in the Season Five finale episode "Our Darkest Hour" and the Season Six premiere episode "The Longest Night".
