Jet skis are meant to be in water, unlike suede pants, silk shirts, and paper hats made from the Declaration of Independence. Hit the waves with today's Groupon: for $49, you get a two-hour jet-ski rental from Cowtown Jet Ski Rentals on Eagle Mountain Lake (a $140 value).

Cowtown Jet Ski Rentals' customers roar across the glassy waters of Eagle Mountain Lake astride powerful Honda AquaTrax jet skis. Before setting clients loose on a lake, experienced pond pilots impart tips and regulations for proper operation of their nautical steeds and help them to suit up in buoyant attire, such as a pair of protective gloves to improve grip, reduce blisters, and shield knuckles during a boxing match with belligerent manatees. Then, customers mount their rumbling watermobiles alongside up to two friends, family members, or sworn Mario Kart nemeses, burning through their included tank of gas during two hours of high-speed aquatic adventuring.
