I think MST3K had the right idea:

“If you’re wondering how he eats and breathes
And other science facts
Just repeat to yourself “It’s just a show
I should really just relax”

Reminds me of Trump and his… frustration with low-flow toilets.

“You turn on the faucet and you don’t get any water. They take a shower and water comes dripping out. Just dripping out, very quietly dripping out,” the President continued, lowering his voice as he spoke about the drips. “People are flushing toilets 10 times, 15 times, as opposed to once.”

Seconding the mythology recommendation! My nine year old loves d’Aulaires’ Book of Greek Myths and was stoked to find a new podcast called Greeking Out by National Geographic Kids. She’s been listening to it practically everyday, and we just picked up the companion book from the library this weekend.

• Unicorn Rescue Society series by Adam Gidwitz
• Ben Yokoyama Cookie Chronicles series by Swanson and Behr
• Wings of Fire series by Tui T. Sutherland
• Wow in the World books by Mindy Thomas and Guy Roz (they have a companion podcast that’s absolutely bonkerballs as well!)

All of these have a nice mix of comedy and mischief/adventure that he might enjoy.
