The Shark Tank: Episode 109

Kevin O'Leary takes a dare from his fellow Sharks and bites into a veterinarian's product that claims to prevent cancer in pets. Later on, the Sharks enter a huge sphere to experience first-hand the entrepreneurs' virtual arcade; and four of the five Sharks hope to talk Barbara out of making what they think is a bad deal. Other business pitches include an outspoken designer from Houston, Texas who challenges the Sharks to invest in her line of fashionable clothing for women.
