Meanwhile, Meemaw (Connie) discovers a terrifying new pest in her yard: hammerhead worms . These real-life invasive flatworms are aggressive, reproduce by fragmentation, and secrete a neurotoxin. When George Sr. tries to help, he accidentally makes it worse by chopping one up—causing each piece to grow into a new worm.

“A Philosophy Class and Worms That Can Chase You” is Young Sheldon at its best. It balances laugh-out-loud moments (George trying to fight worms with a shovel) with genuinely moving character development.
