OK, here's the deal. I play mostly live poker (I use low-stakes online play to practice for my live games, but I profit playing live). On more than one occasion, I have sat at a poker table while a maniac throws his chips into the pot, over and over again. And then he catches some miracle card and takes down the pot. Now was the live dealer dealing non-randomly?

Seriously, poker is full of variance. If you flip a coin enough, you'll come upon a stretch of 10 heads in a row. That doesn't mean the coin is loaded.
