Two mice

Two mice were sitting in the bathroom on the edge of the bathtub. The first mouse looks over to his friend and, referring to the toilet, asks, "Wanna go for a swim?" The second mouse quickly replies. "Oh, no! I'm never going in there again!!!" "Well, why not?" says the first mouse. "Well," starts his friend, "I was in there about a week ago swimming around and minding my own business and all of a sudden it got real dark, it started raining, it started thundering, and if somebody wouldn't have thrown me a log, I would have drowned!"
