Is this entertainment?

Darlene and I have visited many restaurants where they have numerous televisions scattered around with (naturally) various sports channels selected. Inevitably, one of those televisions will be showing a poker game.

Seriously..... who watches poker on TV? Is it really that exciting? I don't see what the draw is. Is it the players trying to dress as super-cool as they can muster? Are you watching to learn how to play? Is it that hard? Is it the thrill of watching people lose their shirts? Could someone please explain it to me?
