Ted: You broke me and Karen up? Are you insane? What gives you the right to do that?
Lily: Ted, I did it for your own good. You just weren't seeing how awful she was. She failed the Front Porch Test.
Ted: What's the Front Porch Test?
Lily: Ted, you, me, and Marshall have been best friends since college. Think about how much we all mean to each other. So when I picture the future, I picture us all together. How we'll all be retired, sipping tea on the front porch of our beach house, playing bridge all day.
[fantasy scene of elderly Ted, Marshall and Lily on the front porch:]
Lily: Okay, bridges are wild. Four of a bridge beats a royal bridge.
Ted: I see your bridge and I raise you three bridges.
Marshall: Bridge! I win!
[present:]
Barney: You have no idea how to play bridge, do you?
Lily: We're gonna take a class.
Marshall: It's important to stay active.
