We have these snakes. We put two of them together, and immediately one wrap the other one up and squeezes it until it explodes. Then we put a different two together, and they do the same thing - it seems to be completely random which one gets the upper hand, but when it does, it squeezes the other until it turns red and its eyes are nearly popping out of its head, and we have to back off and look for shelter so as not to be hit by the flying gore.

Then I'm getting on an airplane.
