I definitely found the titular peek behind the scenes given in this episode very interesting. Actually being able to feel the improv gears turning in everyone's heads as they scrambled to build something cohesive out of Ed's character was actually kind of fascinating.
Part of me wonders, though, why it was even necessary for him to do a character in the first place. I know that the real person/weirdo dynamic is this show's primary format (especially since becoming CBB), but considering Seth and Ed's work history together I think it could have still been a great episode just to hear Scott interacting with both of these guys as real people. Even if it was just a "Broin' Out" style chat, I'm sure everyone involved here could deliver the funny. There are some episodes from the CDR era that did this really well, like the one with Chris Hardwick and Matthew Braunger or the one with Chelsea Peretti and Nick Thune; I would love to see that kind of thing pop up occasionally at some point in the future.
Just to be clear, I don't mean this as a criticism of the show, because as far as I'm concerned CBB has been consistently hitting it out of the park over the past few weeks. Hearing about how the bread is made just got me thinking about this kind of stuff, I guess.
