Shark Tank (2009)

Troy Carter enters the Tank as a Guest Shark. A duo from Dallas, Texas pitch their eclectic sock of the month club subscription while standing in their boxer shorts, but will Sharks jump in feet first? Two men from Tulsa, Oklahoma offer the Sharks an investment opportunity in their unique line of wooden bowties, lapel accessories and men's fedoras; an entrepreneur from Springdale, Maryland has a valet and garage parking app that enables users to pay in advance by credit card; and Nashville-based parents tout the benefits of their grippy balm that keeps eyeglasses from slipping.

Silicon Valley venture capitalist, Chris Sacca, joins the Tank as a Guest Shark. He finds himself in a heated battle with Lori over a tech education business; two sports fans have a home rental website; an entrepreneur with a unique twist on everyone's favorite hot drink; and an inventor has developed a device that can inflate objects in mere seconds. Also, an update on SWAG Essentials, which did not get a deal in the Tank during season 6.

A Christmas-decorating aficionado has a high-tech way to deck the halls with animated glow balls and synchronized musical trees; an entrepreneur has whimsical knit hats, complete with detachable facemask; two Harvard grads have a line of ornate, pop-up greeting cards for all occasions; and two women demonstrate their all-natural deodorant made from activated charcoal. Plus, Daymond John gives a workshop to the principals of four of his companies — Bombas Socks, Sunstaches, Myself Belts, and Cozy Bugs — and brings out chef Rocco DiSpirito to provide some delicious inspiration.

An entrepreneur pitches a smart plate containing food-recognition technology that could solve all your dieting problems; two energetic women have created a sweetener that tastes like honey, but is not made by bees; the Sharks crack up at the sight of an entrepreneur's unique spa business for babies; and a perhaps too-confident Stanford grad believes he's at the forefront of where high tech meets fashion for men's custom shirts. In a follow-up on Ilumi, the company in which Mark Cuban invested in during Season 5, we see how their wirelessly controlled LED lights have illuminated the business world.

Two former advertising guys in New York try to sell the Sharks a cure for cell-phone addiction; emotions rise when entrepreneurs from Orlando, Florida talk about the inspiration behind their wireless cuddly toy that tells science and math stories to children; two pet lovers from Austin, Texas design and customize accessories for the most important member of the family: your one-of-a-kind pet; and two men from Huntington Beach, California hope they can lock up an investment deal with their high-tech "smart" tool box.
