Thanks to the success of his LL Cool J-approved clothing company FUBU, Daymond John knows a thing or two about business, and a thing or three about looking almost as handsome as LL Cool J. Because of his business savvy and handsomeness, he was an obvious choice as a judge on ABC's Shark Tank. Here, he gives his advice on how to win himself, Mark Cuban, and the rest of the school (of sharks) over with your completely awesome idea. How to pitch to investors who have giant teeth that grow back when they fall out Make sure you can break down your entire company in a short amount of time. Know all of the answers, even if it’s just “I don’t know, but one of the reasons I’m here today is that I’m trying to hire someone who knows how to do that.” Always know your numbers...When you pitch to anybody, pitch what's in it for them.

'Cause they need a lot of help. Caffeine products: So hot right now I’ve been seeing more and more energy stuff. Energy spray, energy waffles. Energy’s the new thing...The waffles you can just pick up at the store, and they did not taste good to me. So they stood out to me.
