Lily: You asked her to lunch?
Marshall: Why would anyone, want to have a lunch, with their ex.
Barney: Glad you asked, Marshall. There are four possible motives behind an ex lunch. Number 1, they want to
get back together.
Lily: Oh, like my high school boyfriend Scooter.
[flashback to Lily having lunch with Scooter:]
Lily: Lilies, clever. I'm sorry I don't have a scooter for you.
Scooter: My God, that's funny. I forgot how funny you are.
Lily: Where is the waiter?
Scooter: Why? You like waiters? I can be a waiter. I'm going to be the greatest waiter on this earth, and then you'll love me.
