There was a Peanuts cartoon (four or five panels, a short one) many years ago that began with Linus, Charlie Brown, and Snoopy strolling down the sidewalk. CB was telling Linus about a nature show he’d seen where the mother lion (if i recall correctly) would get her cubs to behave by grabbing the back of their neck and gently shaking them. Linus replied “I don’t see how that could do any good.” In the penultimate panel Snoopy grabbed Linus by the back of the neck and shook him vigorously. The final panel showed the three of them walking, with “vibration lines” indicating Linus’ unsteady gait. He is saying “But it’s possible it could work.”
