You don’t need to be a fan of the series 24 to get the joke here.
I watched it and it immediately made me think that there is a kind of ethnographic method here, perhaps a class assignment: take a familiar case from the contemporary setting and explore it by setting it back 15 years. Change everything you can think of, what stays the same and what makes a difference? Could be a useful way to pick apart the difference technology makes. Or perhaps not, since as EB White says: “Analyzing humor is like dissecting a frog; nobody learns anything and the frog dies of it.”
