"Everything Must Go" is a great How I Met Your Mother episode. In this episode, Barney finds out who has been warning women about him, and it turns out to be Abby. I love how they bond over hating Ted. I love how Abby says she hates Ted, but she's really in love with him. I love how they have a fake relationship to show that Ted is terrible when he's in a relationship. I love how Barney proposes and Abby thinks his proposal is real, so she thinks they're getting married. I loved the Lily and Marshall plot of selling Lily's paintings and it turns out that dogs love her paintings. I give this episode a 9/10.
