From The Lost Media Wiki
An episode recorded during a live event at San Diego Comic con 2017, attendees could participate and pitch an idea to the channel, I was one of the participants and I would like to watch it again, the adult swim site doesn't seem to have anything on it anymore, and using the wayback machine doesn't show the video.
