Quote from Robin in Woooo!
Lily: You're, like, best friends with Jillian now? Robin: It's just... You're married, Lily, but I'm still single. Whenever I hang out with you, I'm usually the third wheel to you and Marshall. Sometimes, it's fun to go out with other single women and do stuff that you don't want to. Lily: Like what? Robin: Like woo, Lily. Like woo. Lily: I can woo. Robin: That's not true. Lily: I can, too. Robin: It's just not you.
