" Good Morning America" is swimming with the sharks of " Shark Tank" as each of the anchors get the chance to pitch a unique product or service idea to the business moguls of the hit ABC show.

Mark Cuban, Barbara Corcoran, Daymond John, Kevin O'Leary, and Lori Greiner held nothing back when it came to evaluating the anchors' pitches and scored each one on a scale of 1 and 5. Who will survive and who will get eaten alive?

George Stephanopoulos jumped into the tank first.

George's Pitch: 'Dad-tionary'

Stephanopoulos made his pitch: "Dad-tionary," an app that's full of the latest kid-speak to help keep dads up to date on the latest lingo, increase their cool factor and bridge the communication gap.

The idea for "Dad-tionary" was born when Stephanopoulos, a doting dad who thought he had a "pretty good grasp of the English language," saw the abbreviation, "IMHO," in a headline and had no idea what it meant. Stumped, his daughter, Elliott, giggled at him and had the answer: "In my humble opinion."

Million-Dollar Product That Got Away From 'Shark Tank'

How It Works When you type a word or phrase into the app (or say one), the meaning of the terms as well as an example of how it could be used in a sentence will come up. There is also a way to store terms you have looked up, quizzes to keep track of progress, and a game where kids and parents can face off against one another.

"This app is personal, practical, and fun - and 'ICYDK' - in case you didn't know - a lot handier than these," Stephanopoulos said, throwing flashcards in the trash, for effect at the presentation. "Who's with me?"

Watch the clip above to see if George will sink or swim with the sharks, and stayed tuned to "GMA" to see what Robin Roberts, Lara Spencer, Amy Robach and Ginger Zee pitch. Viewers will get to vote for their favorite product on GoodMorningAmerica.com.
