(Ted and Marshall turn to look at girl Barney's talking about and notices that it's Lily)
Barney: How much hotter is she than your girlfriend? Go get him, tiger. How embarrassing. Look at her. Ted: No, the real story. Ted: She's not even on the hot-crazy scale. That's crazy. We met in a cooking class.
Plan: A: Ted's new girlfriend; Q: Who becomes jealous of Ted and his friends' story? Summary: Ted's new girlfriend becomes jealous that the story about how Ted and his friends met is better than how she met him, resulting in her ranking on Barney's "crazy scale" to go through the roof.
