Back when I was jacking up my Camry (front-left corner), I was using the scissor jack, IIRC, had blocks under the back of the rear tires, had the ebrake pulled and raised it up fairly high... The car groaned, thought "Hmmm...," it groaned again, and promptly rolled forward off the scissor jack.
Nothing happened to me (thank goodness), but the damn jackstand I was about to slide under the car but a small indention on the side skirt just below the driver's door.
