When Roger is calling the CIA, there is a message on the side of the building that says "Peter was Here." This is a reference to Peter Griffin from Family Guy.
This episode was the last episode to air on Fox, as noted by Stan closing the book entitled "American Dad! on Fox."
When Roger and Blagsnarst are driving in the yellow Volkswagen convertible while listening to the Barry Manilow song "Ready to Take a Chance Again", this is a nod to the opening credits of the film Foul Play (1978) in which Goldie Hawn also drives a car while listening to the same song.
The scene with Roger making a gun with chewing gum and other items is a reference to MacGyver (1985).
