The first three minutes use the same lines from Ferris Bueller's Day Off.
At the end, Brian asks why the audience is still watching and that they should go to bed, just like Ferris asked the audience why were they still in the theater and to go home.
Brian calls the people in the black ops mission "Rooney," "Cameron," and "Abe Froman the Sausage King." Rooney was Dean of students in Ferris Bueller. Cameron was his friend. Abe Froman the Sausage King was the person Ferris impersonated to get into the restaurant for lunch.
When Agent Harris appears to Brian in his mind, she is dressed just like Sloane Peterson was in Ferris Bueller's Day Off.
Brian sings, "Brian, let my people go" ("Brian was in Egypt's land, let my Brian go"), just like Cameron did in Ferris Bueller's Day Off.
