Barney: Beg your pardon, the fabled Slapping Tree of Gongqing Forest?
Marshall: Sure.
Barney: Really? Fabled? Because I've never heard of it.
Marshall: Pretty sure everybody's heard of it. Guys?
Ted: I backpacked there in college.
Marshall: See? Fabled. It even inspired a popular Chinese children's book. It's a poignant parable whose message is if you love someone, set them free. But not before first slapping them right in their stupid face.
