Lizard under my butt!

Picture a lizard body as big around as a liter of soda. The tail is as long as the body making the total length longer than your arm. It looks like a dinosaur. Now you are relaxing while reading a book at the pool on a comfortable lounge chair. You check your peripheral vision as you see the movement. The lizard looks at you. Then it comes over and goes under your chair. You wait for it to come out the other side. It doesn't. You start to imagine that the lizard is going to think your butt is a fruit or food. It is still under your chair. Slowly you move off your chair and look back knowing that you must be crazy. Then you realize that it is true, he is hanging out under your pool chair. Hmm I'm not comfortable sitting back down. Best course of action? Why get the bartender, of course. He calmly comes over and shoos him away. But the bartender is wearing shoes so he can be brave. The lizard has not gone that far away. Now you try to determine how much time you can stay on your lounge chair before you run for home and not looking chicken doing it. Exciting days.
