The flag of Geldar is based on the Canadian flag, with the red maple leaf replaced by an image of Dr. McKay's head.
The disgust of Geldar's people for certain things is related to their Oracle, Rodney McKay, although they don't know about it. They refuse to eat citrus fruits because McKay is allergic to them, and they dislike sunlight because Rodney is afraid of burning himself due to sunlight exposure. In addition, Nola's hairstyle is based on the parameters McKay sets in the program, which closely resemble Samantha Carter's hairstyle.
The slogan "Ask not what Geldar can do for you, but what you can do for Geldar" is based on the famous line spoken by U.S. President John F. Kennedy in his 1961 Inauguration speech.
