Trivia: During filming of numerous episodes, the crew and cast had many problems with airplanes flying overhead, because they were in a flight path. Blooper reels make many references to this.
Trivia: When Sam and Barry are pinned down in the house by gunmen, Sam is making a improvised explosive device. Barry says to Sam, "When are you gonna be done with that boomstick contraption?" This is a reference to the Evil Dead series Army of Darkness, when Bruce Campbell the main character says, referring to his shotgun "This is my boomstick!"
Trivia: In the final episode every character says the line they said in the opening throughout the episode. Fiona: "Shall we shoot them?" Sam: "You know spies, bunch of bitchy little girls." Jesse: "That's how we do it, people." Only difference is Fiona is the one who says "My name is Michael Weston. I used to be a spy."
