The Simpsons Season 38 Episode 5 photosairing tonight, Sunday, November 1, from 8:00–8:31 p.m. ET/PT on FOX . Lisa’s decision to undergo an evaluation leads her to look at familiar people in Springfield a little differently.
Yeardley Smith voices Lisa Simpson, with Dan Castellaneta as Homer. The series’ voice ensemble also includes Julie Kavner, Nancy Cartwright, Hank Azaria and Harry Shearer .
What Is “Testing 1-2-3” About? Lisa has herself evaluated for three types of neurodiversity, insisting that she is not simply trying to secure extra time on tests. As she learns more, the behaviors under discussion remind her of things she has observed in Principal Skinner, Comic Boy and Homer.
The episode’s premise turns a personal question into a wider look at Springfield. Lisa begins connecting what she hears during the evaluation with people she already knows, raising the possibility that behaviors considered atypical may be more familiar than they first appear.
FOX’s preview does not name the three types being evaluated or reveal Lisa’s results. Those details, along with how her observations affect the other characters, remain part of tonight’s story.
