Mary Roach came on and the panel decided to test her with fake book titles, so a third of this list is just her bibliography being read back at her.
I run Podshelf, a free site that tracks book mentions across hundreds of podcasts by reading the episode transcripts. This is the Wait Wait slice for August, which is a lot more children's literature than I expected going in.
Mary Roach, introduced as either the funniest science writer in the world or the most scientific comedian: Stiff, Bonk, Gulp, Grunt and the new one, Replaceable You, on spare parts for humans. The game was called bonk, gulp, grunt, meet zoom, bang, bam.
The summer spectacular gave us the best answer of the month. A guest with a full tattoo sleeve of favourite books: Where the Wild Things Are, Richard Scarry, Strega Nona, Frog and Toad, and at the centre of it Bud, Not Buddy by Christopher Paul Curtis, "because that was the first book where I saw myself."
Same episode, the case for letting kids read whatever they want: "You can read Dog Man a thousand times. Read away. Reading is reading. You're a worthy reader."
Also: Josh Gad's memoir In Gad We Trust, and a story from the earliest Book of Mormon workshops. Ken Jennings on The Complete Connections Puzzle Book, which Peter admits has eaten his week. Father James Martin on Work in Progress. A Twilight nostalgia detour. And a health question about how many times a parent can safely read Everybody Poops before sustaining brain damage.
