Let’s break down what works, what happens, and why this episode sticks with you. The episode juggles two main storylines, but one clearly takes the emotional lead.
If there’s one thing Young Sheldon does better than most sitcoms, it’s sneaking up on you with profound life lessons wrapped in awkward pre-teen moments and bizarre science facts. Season 4, Episode 14—titled “A Philosophy Class and Worms That Can Chase You” —is a perfect example. young sheldon season 4 episode 14
But look closer: The worms are unkillable pests. They represent the messy, persistent problems of life—the things you can’t simply cut away or solve with brute force. Much like the fear of death in Sheldon’s storyline, the worms keep coming back no matter what you do. Sheldon has always been portrayed as emotionally distant, but this episode gives Iain Armitage a chance to show real vulnerability. When Sheldon realizes that he—and everyone he loves—will eventually die, he doesn’t just shrug it off. He panics. Let’s break down what works, what happens, and
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.

The Hammerhead Worms Are a Genius Metaphor On the surface, the hammerhead worm subplot is hilarious. George Sr. panicking, Meemaw refusing to back down, and the sheer ridiculousness of “worms that can chase you” (they move fast!) is peak sitcom gold.

“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. It doesn’t solve the problem of death—how could it?—but it suggests that maybe the answer isn’t a formula or a faith. Maybe it’s just showing up for the people you love while you can.
It’s a rare moment where Sheldon doesn’t need a fact. He needs a hug. While Missy doesn’t have a major A-plot here, her brief scenes are gold. When Sheldon is rambling about mortality, Missy deadpans: “I’m going to die of boredom listening to you.” Later, she perfectly sums up the episode’s theme: “You can’t stop living just because you’re gonna die someday.”
Meemaw, after failing to kill the worms: “I’m not afraid of dying. I’m afraid of those worms outliving me.”
