Get ready to hum along, because once these songs start… they never leave your head! This week, we take a nostalgia-packed trip back to Schoolhouse Rock, the beloved Saturday morning shorts that taught us multiplication, grammar, science, and American history—all with the help of some ridiculously catchy tunes.

From Three Is a Magic Number to I’m Just a Bill, we revisit the songs that shaped our childhoods, share the funny ways they stuck with us (yes, we all sang the Preamble in class), and test each other’s memory with a fill-in-the-blank quiz. Along the way, we talk about how the series came to be, the surprising musicians behind the music, and why Schoolhouse Rock still resonates today.

Warning: you may leave this episode singing about nouns, gravity, or mashed potatoes. You’ve been warned.
