Click on the Barry's Blog logo above, and you will be taken directly to the site where you will find Part IV of the video of the Dinner-vention conversation. Once you get to the site itself, you can scroll down to watch previous parts if you want. If you are on the site, Part IV is below.
Note: Margot Knight's name is inadvertently misspelled in the credits, omitting the "t" and erroneously listing her as "Margo". I deeply apologize to her for that error.
