Marshall: This is bad.
Lily: Yeah.
Marshall: We've gone nine years without peeing in front of each other. You always think there'll be more time.
Lily: Look at us. We're basically an old married couple, and we're not even married yet. The flame of our romance is flickering, and if I pee all over it, it might go out forever.
Marshall: How much longer do you think you can hold it?
Lily: I drank a Big Gulp of Mountain Dew during that Quantum Leap marathon.
Marshall: Oh, boy.
