It was once thought that Friday night was the graveyard of television where shows were left to die. That's not the case for ABC's "Shark Tank," where hopeful entrepreneurs bring products to the top business men and women (a.k.a. "The Sharks") in hopes of seeing their dreams come true.

Our Jim Halterman stepped cautiously into the "Shark Tank" recently to chat with Sharks Lori Greiner, Robert Herjavec, Kevin O'Leary and Daymond John to find out how they keep from getting swayed by the emotional stories of those pitching ideas, why the show is such a hit and which Shark has the tendency, according to O'Leary, to buy products "like a drunken sailor."

"Shark Tank" airs Fridays at 9:00/8:00c on ABC.
