Betty Boop and Little Jimmy 1936

In an attic cluttered with 1930s vintage exercise gear, Betty Boop and Little Jimmy try to stay in motion as a playful blend of music and motion unfolds.

Betty belts out the cheerful tune Keep Your Girlish Figure while Little Jimmy answers with a cheeky verse:

Keep Your Girlish Figure

If you’re thin, don’t worry over that. Just begin to laugh and you’ll grow fat

This lighthearted exchange sets the tone for a routine that fans out into comic misadventure as they toy with the old equipment.

Betty’s attempt to use a belt-style exercise machine goes awry when the control sticks. She sends Little Jimmy to fetch an electrician, but his errand keeps morphing into a parade of distractions—magician, politician, musician—each stop adding to the neighborhood’s slapstick chaos. The chase culminates when he stumbles upon an old spring mattress. He tears out the springs and straps them to his feet, transforming into a bouncing, spring-loaded figure.

He rockets through the streets, ricocheting through a market canopy, then soars back toward Betty’s house and up to the attic window. In a comic twist, his spring-powered flight pulls the plug from the exercise machine, breaking the spell that made Betty look pencil-thin. By that moment, Betty’s figure has become fearlessly exaggerated—slender to the point of comic distortion, with a huge head and spindly limbs—so amusing that she, Little Jimmy, and the surrounding furniture laugh non‑stop until the pair blows up to balloon-like roundness.

The entire scene unfolds with a buoyant sense of whimsy, leaving the characters in a heightened, cartoonish finale that sticks to the playful spirit of mischief and transformation.
