There's no guessing the connection this time. Michael, Mark, Dave, and David get together for an impromptu look at Prince's three movies.
David the Younger takes the reins this episode to fly us through Harrison Ford and Tommy Lee Jones in The Fugitive, Hiccup and Toothless in How to Train Your Dragon, and Rocket and Groot in Guardians of the Galaxy. But no, the secret connection isn't that they're buddy movies. Take a listen and see if you can guess what it is before David reveals it at the end.
