When hitting or tapping on an electronic device of some kind suddenly solves what ever it was that was preventing it from working properly, or changing the song on the jukebox to Elvis Presley's Hound Dog.
Fonzie would at times demonstrate an almost magical ability to manipulate technology with just a nudge, bump or a snap of his fingers (The Fonzie Effect) for things such as starting a car, turning on lights, coaxing free sodas from a vending machine, making girls respond, or changing the song selection on a jukebox - occasionally pounding one with his fist and eliciting the response of a classic 1950s tune, such as the Elvis Presley song Hound Dog.
