Future Ted: [v.o.] Oh, you know what? I should explain why Lily was angry. Six years earlier, a few weeks after their wedding, Marshall and Lily were going through their gifts.
[flashback:]
Lily: That's weird. Did Ted get us anything?
Marshall: Come on, Lily, I mean, Ted's our best friend. If his gift hasn't arrived yet, it's on the way.
Future Ted: But time passed and no gift arrived. Finally, Marshall started dropping hints.
[flashback to a few months after the wedding:]
Marshall: Hey, man, it was great having you at our wedding.
Ted: Thanks, bro. And thanks for this coffee. It is great.
Marshall: You were not wedding absent. No, sir. You were wedding present.
Ted: Do I detect a note of hazelnut?
Marshall: [chuckles] Wedding present. [later] I think he got it.
