Barbara Corcoran and Lori Greiner ran the negotiation table during the 100th episode of ABC's 'Shark Tank,' scoring the only deals of the day.

The first deal went to a brother-sister team seeking $200,000 for 10 percent of their miniature popcorn company, Pipcorn. The all-natural snack is an organic, gluten-free and vegan alternative to popcorn that founders Jeff and Jen Martin say won't get stuck in your teeth. 

Pipcorn launched in April of 2012 and a month later was featured as one of Oprah Winfrey's "Favorite Things." The endorsement helped Pipcorn generate $200,000 in sales last year and has put the company on track to reach $440,000 in revenue in 2014. Despite Pipcorn's strong growth during its first two years, the sharks weren't biting on the company's $2 million valuation.

"There's nothing proprietary about the [popcorn] seed," said Kevin O'Leary. "I don't care what they say. You're not worth $2 million."

While Robert Herjavec agreed the company was overvalued, he saw promise in the business and offered the full $200,000 for 10 percent. The Martins had other ideas, however, choosing to partner with Barbara Corcoran, who matched Herjavec's offer but required a 10 percent cut of all profits until making her investment back.

"We've seen Barbara do a ton of food [deals]," Jeff Martin said. "We targeted her from the very beginning."

Next into the tank was a mother-son team with a bizarre but popular medical device called the Squatty Potty. The product is designed to relieve colon issues such as constipation and generated $2.7 million in sales during just its second year of business. Co-founders Judy and Bobby Edwards asked the sharks for $350,000 for 5 percent, explaining that the company had $7 million in projected sales this year.

After Herjavec passed on the business, the Edwards fielded offers from O'Leary and Lori Greiner, ultimately partnering with Greiner, who bid $500,000 for 10 percent of the company.

"We can make a crap load of money here," said co-founder Bobby Edwards.

The final pitch of the episode came from chef Heidi Lovig, whose company Heidi Ho makes a variety of dairy-free cheeses made entirely from organic nuts, seeds, vegetables, herbs and spices. Lovig came to the tank seeking $125,000 for 20 percent of her company, but ultimately gave up 30 percent of the business, as Greiner landed her second deal of the day.
