Yes, the sequel to 'Piranha 3D' is called 'Piranha 3DD.' Are you really surprised? And now there's a new racy trailer. Lets just say the '3DD' in the title doesn't just refer to the optical tricks used in the film. 

This time the killer fish are attacking people at a water park. And who shows up to save them? David Hasselhoff! Judging by the quick glimpse of the Hoff in the teaser trailer below, it's safe to say he's playing himself.

All the elements of the modern horror movie are represented in the clip: clueless coeds partying, vicious monsters attacking people in graphic ways, dark humor and bikini-clad women with gigantic fake breasts running around in slow motion.

The film also stars Ving Rhames and Gary Busey (!). For once, Hasselhoff isn't the sole joke stunt casting. Check out the NSFW trailer for 'Piranha 3DD' below.
