Sadistic grindhouse throwback 'Piranha 3D' didn't have nearly as big of a splash as The Weinstein Company probably hoped upon its release last year. After all, between Funny or Die videos and flying penises, 'Piranha' was everywhere, and that still only equaled $25 million at the domestic box office. The cheapie thriller earned double that overseas, though, making the sequel, 'Piranha 3DD,' seem reasonable. Good thing, too, since that's the only thing reasonable in this bananas new teaser trailer for the film. Hello, David Hasselhoff, giant silicon breasts and machine-gun legged Ving Rhames!
