Over the summer, Greg did a massive, seven week tour of Australia. Walking the Room is, incredibly, massive Down Under, to the point where they’ve done live, sold-out theater shows and have a rabid online fan base. Dave was accepted to do his one-man show at The Melbourne International Comedy Festival, and his online Kickstarter raised the funds to send him in under 24 hours. A podcast as real and honest as Walking the Room – which was essentially about two comedians struggling and failing – would become the pinnacle of dishonesty if they continued with it in light of their recent successes.
Keter-class Objects are broadly defined as "inimical threats to all of humanity", and are listed along with Humanoids and Jokes as concepts that are difficult to write because the process of coming up with something that is broad-reaching enough to threaten all of humanity while allowing the Foundation to maintain the veil of secrecy and being an interesting read is surprisingly difficult. While a planet-sized monster that can swallow the earth in one gulp might certainly be classified as a Keter-class entity, it would be almost impossible to write it in such a way as to be plausible (within the Foundation's literary framework) and interesting.
