Transcript for 'Shark Tank' Entrepreneurs Give Back
Narrator: "Shark tank" has had its share of bizarre pitches. Oh, my lord. Aah! Man: What up, baby? Who's ready to get comfy with me? I'm the president and founder of fat ass fudge. Herjavec: Oh, my god! Narrator: And some sexy ones, as well. It is the only wedge-tight pillow on the market for women with implants or with large breasts. Greiner: I knew this was one that the guys would want to get their hands on. Narrator: And while the sharks often agree on which products deserve to be laughed out of the tank... Both: We live and breathe balls. 24 hours a day. Narrator: When it comes to business philosophy, there is rarely a consensus. The DNA of a business is to make money for its shareholders, not to save the world. I'm the opposite of Kevin. Kevin -- it's all about the money, and for me, it's not all about the money. It's about doing good, giving back, and helping others. Narrator: Many entrepreneurs agree with Lori and make giving back a key component of their companies. We started a jewelry line unlike any other. For these former U.S. Army officers and real-life sisters, dog tags are not the only accessory they like to show off. Before going on "Shark tank," we had about $50,000 in sales, and now since "Shark tank," we have over $2.5 million in sales. All of that successful has motivated the ladies of the jewelry company Stella valle to give a portion of their earnings to the veterans' organization team red, white & blue. Jung: It's all about taking veterans and getting them that physical and social interaction with everyone else in the community. We not only have a beautiful jewelry line, but we have a mission that helps others. Our company is tipsy elves, and our slogan is "Not your mama's Christmas sweater." Narrator: The guys behind the ugly-christmas-sweater company tipsy elves also made giving back part of their company's mission. Robert, we accept your offer. Excellent, guys. Narrator: A portion of their proceeds from every single sweater they sell goes to a child in need. Anything can help, and something tangible like a sweater to give to a kid at Christmas when it's cold, I think it's very reasonable. Narrator: When Rick and Melissa Hinnant pitched their charitable-minded sock company grace & lace, there was no hint of the company's painful origin. Melissa: I was about halfway through the pregnancy. And I was suddenly told that I was gonna deliver a baby, and... She wouldn't survive. Narrator: In an attempt to save their baby girl, who they had named Hallie, Melissa was put on strict bed rest. I laid on my back in that hospital bed for weeks. Narrator: To pass the time, she began knitting. And I crocheted Hallie a blanket. Unfortunately, we -- we lost her. They weren't able to To stop the contractions, and she didn't make it. She didn't make it. Rick: I told Melissa -- I said, "We can be bitter and ask that question, 'why me?' "Or we can choose to move forward knowing something good is gonna come out of this." Narrator: And something did. After discovering her talent for knitting, Melissa made a pair of frilly boot socks, and grace & lace was under way. Since partnering with Barbara, their business has grown exponentially, enabling them to give back. The first major goal was one orphanage in India that would take 50 orphans off the street, and with the success from the show, we're able to do two orphanages. We're naming these orphanages the Hallie house in honor of our daughter. If someone has a great generosity of spirit, it multiplies. They always make money. It's just the way it is. Narrator: There may be no other entrepreneur who better embodies generosity of spirit than Johnny Georges, the inventor of water-saving irrigation device the tree-t-pee. Why only $5? O'leary: It's got to be $12. Why not charge $10 or $12 or $15 or $20? Georges: Because I'm working with farmers. I work for farmers. It's what I do. And helping them helps us all. People don't realize food don't grow on the shelves in the grocery store. It grows out here where we are. Narrator: Guest shark Jean Paul dejoria agreed. When Johnny said that this tree-t-pee saves 3,000% on water -- you only use 1/30 the water -- that's when I knew this is good for farmers. It's good for America. I want to be this guy's partner. Narrator: But it was after Johnny had closed the deal that he really captured the hearts of all the sharks and the country. Johnny, tell your dad he's a great man. He died 12 years ago. Greiner: Aw. He's still a great man. He made me who I... We work hard...every day. I worked for that man for 20 years. I thank god that I got to work with that man. He's an innovator. He taught me everything I know. He was hard on us, but nobody owes you nothing'. Life is what you make it. He taught me that, and he was a great man. He came from nothing'. Narrator: Since appearing on the show last November, Johnny has been traveling the country, showing farmers what the tree-t-pee can do and making deals. Man: How -- how many trees do we have? Well, it's 700,000. We'll take 700,000. Yes, sir. I'll make you the deal of a lifetime. All right. And just recently, the biggest news of all -- a deal with powerhouse retailer Home Depot. All right, boys, let's do it! Narrator: These days, Johnny can't help but wonder what his father would've said if he had lived to see his son's success. Georges: He is here. He lives on in me. I hope that he'd be proud. Narrator: Up next... What happens when the sharks turn on each other? Shark fight, shark fight. Do not screw with Mr. Wonderful. The sharks were fighting, and that's for real. Narrator: But first, what do the sharks really think about Robert herjavec? Herjavec: She's a great lady. If she needs a helping hand, I'm happy to be there. Robert's the "Kumbaya" guy. That's so disrespectful. I mean, the guy's a nice guy. Why wouldn't you help the guy out? Who cares about all that crap? What does that have to do with anything? Robert is just syrupy. I came here and worked in a factory. I remember My first job. People made fun of him... Because he wasn't American. 'Cause I'm Croatian. And they called him all kinds of names. And when I say the word "Croatian" I have to cry. Robert is a more sensitive, feeling person, and I like that about him. Robert has a wacky strategy. Corcoran: Oh, my god. I love this dog! If it looks like fun, Robert jumps in there. Man: That's it, that's it. He's like a little boy in a candy shop. Oh, that is so cool! If you have a fun product, he's gonna jump in. Whether it makes money or not, he doesn't care as long as he can have fun. Whoa! We're jamming, baby! Whoo! ? The rich ? John: He is happy. As nice as you think he is, he's a very, very vicious shark. I'm a very nice guy,
