A young woman was in the hospital, recovering from major surgery. She hated being stuck in the tiny little room and the daily routine was starting to get to her. Every morning, the nurse would bring her breakfast (which always consisted of an egg, piece of toast, and glass of apple juice). She would return later to empty the urine bottle.

"Obviously, you enjoyed your breakfast, but something must be wrong because this looks a little cloudy," he said, pointing to the urine bottle.

"Oh, really?" she replied, picking up the bottle in question and putting it to her lips. "In that case, we'd better run it through again..."
