Future Ted: [v.o.] Kids, back when we were younger, your Uncle Marshall and I were really into college basketball. Every year, March Madness would take over the entire apartment.
Robin: [entering] Hey. What's with the blackboard?
Ted: It's our NCAA bracket.
Marshall: Big board equals big luck!
Lily: Hey, that looks familiar, where did you get it?
[flashback to Marshall arriving at Lily's classroom with flowers. The only person there is the cleaner]
Marshall: Hello. Uh, I'm looking for my wife, Ms.Aldrin.
Cleaner: There's no school today. It's Saturday.
Marshall: Of course. How could I forget?
Cleaner: Dumb ass. [exits]
[Ted comes in and helps Marshall take the blackboard]
Ted: Big board!
Marshall: Big luck!
[present:]
Marshall: We found it. No big deal.
