Dimension Films is doubling your pleasure with a second helping of boobs, blood and killer fish in this summer’s Piranha 3DD. For a while now, I thought the extra D was a cleverly disguised breast joke, but apparently it stands for “David,” as in David Hasselhoff. This new clip from the film features The Hoff in his oh-so-familiar role as a lifeguard. Fans of the glory days of Baywatch will get a kick out of the segment and the humor aimed at an aging Hasselhoff is spot-on to what you can expect from Piranha 3DD. Be sure to check out the trailer, red-band trailer, posters and images, as well. The film stars Danielle Panabaker, Matt Bush, Chris Zylka, Meagan Tandy, Katrina Bowden, David Koechner, Christopher Lloyd, Ving Rhames, Paul Scheer, and Gary Busey. Piranha 3DD opens June 1st. Hit the jump to check out the new clip.
