This episode is all about Anna, I think. Actually, we record these up to two weeks in advance and I'm pretty sure it's all about Anna. Oh! It's also about paying tribute to (and kind of ripping off) The Karate Kid and some really dumb misunderstandings. And Anna. Did we mention Anna? She's in this episode a lot.
Episode description from Hulu:
