Other mistake: As Dark Helmet says his line "Everybody knows that!", watch the crewman in white to Helmet's right. He starts to cover his crotch a beat too soon.
Computer: This ship will self-destruct in exactly ten seconds. Counting down. Ten, nine, eight, six.
President Skroob: Six? What happened to seven?
Computer: Just kidding.
Trivia: President Skroob's name is an anagram of Mel Brooks' last name.
Question: When Dark Helmet says that there are two sides to every Schwartz, is this an obscure reference to something else, besides the obvious light side and dark side of the force?
Answer: "There are two sides to every sword" is a common saying.
