A Leaky Drain

A friend of mine awoke one morning to find a puddle of water in the middle of his king-size water bed. In order to fix the puncture, he rolled the heavy mattress outdoors and filled it with more water so he could locate the leak more easily. The enormous bag of water was impossible to control and began rolling on the hilly terrain. He tried to hold it back, but it headed downhill and landed in a clump of bushes which poked it full of holes.

Disgusted, my friend threw out the water-bed frame and moved a standard bed into his room. The next morning, he awoke to find a puddle of water in the middle of the new bed. The upstairs bathroom had a leaky drain.
