Moira (Catherine O'Hara ) states that Sandra Bullock had to fight to keep the "Speed" movie franchise alive. This is an inside joke. In a 2000 interview, Sandra Bullock jokingly referred to the sequel to Speed Speed 2: Cruise Control (1997) as "the biggest piece of crap ever made."
When David is wary about the ropes course, Patrick says, "Patrick: David's never done anything like this before. Ted jokes, "Uh oh, we've got a virgin!," and David replies, "okay, you might wanna talk to half my Birthright trip about that." "Birthright" is Taglit-Birthright Israel, an educational organization that sponsors free trips to Israel for Jewish young adults (ages 18 to 36). This reference to David's Birthright trip is (along with other episodes' mentions of David's Bar Mitzvah and Alexis's Bat Mitzvah) another sign that the Rose children were raised Jewish. In the final episode of season 4 David states that they are half Christian, half Jewish.
