Quote from Barney in Purple Giraffe
Ted: I got it! I don't ask her out. I invite her to our party next Friday. Marshall: We're having a party next Friday? Ted: We are now. Casual. Barney: Yeah, 'cause nothing says casual like inviting a hundred people over just to "Mac" on one girl. Oh, and Lily, that's my leg. Lily: You waited five minutes to tell me that?
