Here's my submission for the Illustration Friday topic of subtract. It reminded me of a friend who had a couple of pet geckos. One day while cleaning the tank they got loose, and he chased one into the bathroom. As the little guy scurried behind the toilet my friend grabbed him by the tail, which promptly detached from the rest of the gecko. Now, while this is supposed to happen to help protect lizards from predators, it's not a good thing.
The geckos tail never quite fully regenerated, but grew into a weird red stub. The gecko himself was never quite the same either. He didn't live very long, and was always slow and sickly.
Sorry for the depressing story. But on the bright side - there's a silly illustration to look at.
