When not working on maintaining the GTL image, the Jersey Shore cast is, of course, showing that image off during amazing opportunities that they don't deserve to have. Vinny, The Situation, Pauly D, and the rest of the infamous MTV celebs were scene off the coast testing out one of the hottest summer toys: a water-propelled jet pack. Check out the crew enjoying the strange-but-awesome invention. Our favorite is Vinny's face in the sixth picture.
