Anyone Watch Shark Tank?

I came upon this one a few weeks ago and now I'm hooked. It's about fledgling business owners needing funding from a panel of millionaires/billionaires to fully launch their companies. I find it very interesting how these successful "sharks" can so quickly size up the possibilities and say yey or nay. What's ultimately the draw is the personalities of the panel and how they sling arrows among each other. Quite entertaining.
