In Episode 89, Dave and Matt have the insane privilege of talking to PUP's remarkably well-read frontman, Stefan Babcock, whose year-end reading list hit PUP's Substack on December 28th, and is full of great books.

In addition to talking about Stefan's year in reading, we delve into the literary influences and qualities of PUP's discography, discuss skateboarding in mid-life, and manifest a Tim Robinson/PUP collaboration for 2026.

Dave and Matt will be back soon with a Part 2, talking about their year in reading, and you can look forward to 30 more bonus minutes with Stefan through our Patreon, coming in about two weeks' time.

N.B. this episode probably breaks our record for most swearing, as expected. 🤘
