I only watched one episode (this one, for those who must have their fatal curiosity sedated) and it was enough.
The intro has a whiplash. The sister lifts her hands and there's a whiplash. The dog lifts his coffee mug and there's a whiplash. The dad puts his hands on his hips and there's a whiplash.
Welcome to the Johnny Test universe, where every movement you make is followed by a whiplash. The same exact sound used. You can't escape it.
