The chalkboard at the meeting says "There is a crack in everything, that's how the light gets in' this is a quote from the Leonard Cohen song "Anthem".
This episode didn't feel like it followed the formula from a lot of the prior episodes at all and that's a great thing. Not that the show isn't great but the change up was a nice change for the characters.
I wasn't sure where the show was going in the prior episode with the continued mentioning of a band that does technically exist but that wasn't their music. The fictional band makes much more sense now and for a good reason.
Not only was this a funny episode but it brought Lissie into my awareness and now I'm listening to all of her music on Spotify. Great bonus feature for an already enjoyable show.
