Ted: No, dude, hold on. You're not going anywhere. It's trilogy time.
All: [cheer]
Future Ted: [v.o.] Kids, here's the deal with trilogy time. It all started a long time ago in a dorm room far, far away. Dude, if we fail this econ final, for the rest of our lives we're not gonna be able to...
[flashback to Ted and Marshall's dorm room:]
Marshall: Dude, if we fail this econ final, for the rest of our lives we're not going to be able to... We won't know how to... Do you even know what econ is?
Ted: No idea. We're screwed. But there's only one thing left to do at at time like this. Watch the entire Star Wars trilogy all the way through because I haven't done that in, like, five years.
Marshall: Dude, you can't let that happen. If you're not trilling it at least once every three years, the Dark Side wins.
