"It's alimentary, my dear Watson."
Sherlock Holmes' wife being very neglected took to compensatory eating and put on an enormous amount of weight.
The master detective took her to his friend Dr. Watson for examination. After the doctor had given her a thorough examination, Holmes asked him, "What is the problem, doctor?" Dr. Watson replied, "Alimentary, my dear Holmes!"
Watson, Sherlock Holmes's faithful assistant, asked, "What's a ten-letter word meaning 'supplying nourishment'?"
Sherlock replied, "Alimentary, my dear Watson."
