Young Sheldon

CBS | 8:00 pm

After Sheldon’s (Iain Armitage) close friend and mentor Dr. Sturgis (recurring guest star Wallace Shawn) suffers a severe nervous breakdown, a worried Mary (Zoe Perry) begins to fret that her intense and ambitious little boy is heading down the same unhappy path as Season 3 opens with "Quirky Eggheads and Texas Snow Globes." Meanwhile, Georgie (Montana Jordan) accidentally discovers he has the makings of an ace salesman. Lance Barber, Annie Potts and Raegan Revord also star; Jim Parsons narrates.
