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.Here's a new clip from director John Gulager's Piranha 3DD, after the synopsis:

Having awoken from their spring break extravaganza at Lake Victoria, the swarm heads upstream where they look to make a meal out of Big Wet, a local water park where when it comes to fun, nobody does it wetter! Though they came to get wet, get loaded and get some, the staff and patrons get more than they bargained for when they must face the fiercest, most bloodthirsty piranhas yet. Lead by the strong-willed, studious Maddy and her friends, Barry and Kyle, the trio must dive in and take on these man-eating creatures using every ounce of their being…but can they be stopped? Shot in 3-D and feauturing Esquire Magazine’s “2011 Sexiest Woman Alive,” Katrina Bowden and the return of Christopher Lloyd, Paul Scheer and Ving Rhames alongside fresh bait Gary Busey and David Hasselhoff, the film that took an $80 Million bite out of the box office is back for more…only this time it has double the terror and double the D!
