Meet Merton #18

Merton’s latest scheme backfires when he tries to eavesdrop on girls’ locker room chatter using a recorder, only to accidentally play back the very voices he was spying on—leading to a hilarious public reckoning. The prank spirals as his classmates, furious and amused, replay his own voice from the tape, turning the tables on him in a series of escalating gags.

Merton’s new Italian hairdo draws attention from everyone—especially his sharp-eyed friend Marcia, who’s determined to point out every tiny detail he’s missed. When Marcia storms in furious over a misunderstood gesture, Merton’s family is left scrambling to figure out what’s really going on, all while a mysterious package delivery leads to a series of escalating mix-ups.

Merton and his friend Marcia attempt to impress a visiting executive from Major Motors by demonstrating a mysterious "magic pill" they claim can run a car on water—only to accidentally use gasoline instead, causing a chaotic explosion. When the executive arrives, he’s baffled by their wild invention, and Merton’s dad is furious about the mess, but the boys aren’t ready to give up just yet.
