What is the name of the person who says "Make a fist"?
Popeye & Olive Oyl stroll happily along arm-in-arm and stop short when Popeye catches sight of a roller rink: Good Skates 50 cents, Cheap Skates 25 cents the  declares. Asked to go skating, Olive protests that she does not know how; but Popeye will teach her! Within, the attendant asks Popeye what size of skates he wishes to rent, and Popeye, observing Olive's long feet, blushes, either not wishing to say or not knowing. "Make a fist," he suggests to his best girl, and the attendant shall measure it. ("A hand like a foot and a half," he mutters, deftly wrapping a skate about the lady's great clenched hand.) The long, long, slender skates procured, Popeye hammers them with his brawny fists to the bottom of Olive's shoes; she falls over a couple of times as Popeye delicately slips on his own. We roll over to the rink proper, and Popeye, swinging his arms as if rowing a canoe, a bit too gracefully demonstrates the proper technique; Olive attempts to move, but can only kick the air in desperation and flap her skinny arms as she falls headfirst into the railing around the rink. She frees her head by her own strength, but her feet, fanning out, become stuck in the same way as a result: with a struggle, one foot is freed, and an exasperated Olive is helped at last by Popeye, who gently releases the other foot and dusts off his indignant companion (adept enough to tap her foot impatiently), and he points out all of the other rinkgoers merrily whizzing about.
