In the scene on the "Caspian Queen," when Frasier (Kelsey Grammer) hands Peter's business card to the Russians, the dialogue between the two Russians is best translated as: "He's had some business cards made." "What an idiot, eh!" Later when Frasier stipulates how much caviar he wants: "Get me another can."
Five pounds of caviar at $80 per ounce is $6400.
The episode title is a play on the title of the 2002 movie "Road to Perdition."
The storyline that involves Marty's bank problems is very similar to Phoebe's bank "problems" on an episode of "Friends."
Although the French shopkeeper, Robert (François Giroday) is the same as in Season 5's "The Perfect Guy (1998)," the layout of the store itself is completely different.
