A man saw an elderly couple sitting down to lunch at a fast food place.
 He noticed that they had ordered just one meal, and as he watched, the
 older gentleman carefully divided the hamburger in half, then counted out
 the fries until each had half of them.
 
 The old man then began to eat, and his wife sat watching, with her hands
 folded in her lap.
 
 The young man decided to ask if they would let him buy another meal for
 them so that they didn't have to split theirs.
 
 The old gentleman said, "Oh, no. We've been married 50 years, and
 everything has always been and will always be shared, 50/50."
 
 The young man then asked the wife if she was going to eat, to which she
 replied, "Not yet. It's his turn to use our teeth.
