Shark Tank

ABC | 8:00 pm

Some clothing is designed to accentuate certain parts of the body, and in this episode, Dallas newlyweds present their fitness-wear concept that … well, let’s just say that it’s engineered to butt in. Two California friends offer their unique twist on the traditional wine glass, and a Hawaiian scientist and surfer — not the most common of combinations — introduces an innovative rescue signal. The Sharks include Mark Cuban, Lori Greiner and Daymond John.
