Iguanas are good with their tails too. I've had my share of nasty red welts.

Ever see tokays in the wild? I was vacationing in southern Thailand a while back and was staying in this little beach/jungle bungalow. A cool little place that, sadly, was most likely washed out to sea in the tsunami. Anyhow, there were these little generic gecko's everywhere. We would sit out on the patio, getting high, and watch them run around the light chomping down whatever bugs flew by. Suddenly this big fat tokay comes running out and gobbles up two of the little geckos before they knew what hit them. Quite a show for stony eyes.
