A man walks into a McDonalds.

He sees an elderly couple with one Happy Meal. They take out all of the food, lay it out on the table, and start splitting it. They split the burger in half, split the fries into two equal piles, etc. But what strikes the man as odd is that only the husband begins eating.

So the man walks over and says, "I can buy you another Happy Meal if you like."

The elderly woman replies, "Oh no, we share everything."

The man waits, and only the old man continues eating. The woman sits there and watches.

So he goes back over and says, "Ma'am, I would be *honored* to buy you another Happy Meal."

"Oh no," she replies, "you misunderstand. We share *everything*."

Slightly exasperated, the man asks, "Then what are you waiting for?"

The elderly woman replies, "The dentures, of course!"
