A man living close to Dallas, Texas entered his bathroom one day and discovered a baby possum staring up at him from the depths of the toilet bowl. The cute little fellow was drenched and breathless (he would have had to have managed somehow to travel through 50 feet of water filled pipes). So the man did what any animal lover would do, he slammed the toilet lid down on the little fellow and called animal control.
And when it comes to snakes, if you aren’t a snake-lover, these two stories will definitely unnerve you. In Australia a man discovered a python practically twice his size curled up nice and comfy in his toilet bowl. That was nothing compared to the Texas mother who found a 12 foot long python in her bathroom. The creature then proceeded to slide on into her bathtub. Bubbles anyone? (source) (source2)
