Non-parents may only be hazily aware of Dav Pilkey's long-running series of graphic novels devoted to the adventures of Dog Man, a police officer with the head - and brain - of a dog. If this sounds stupid, it's meant to be (in a further meta move, the books are supposed to be written by George and Harold, the goofy tween protagonists of Pilkey's older Captain Underpants books). Anyway, you either know this already or it's completely irrelevant to you, but long story short, there was an off-Broadway musical made in 2019 that got good reviews, and now it's headed to London.
